To evaluate 4^3 / 3, we first need to understand what an exponent means. In the expression 4^3, the base is 4, and the exponent is 3. This notation signifies that 4 is multiplied by itself 3 times. Therefore, 4^3 is equivalent to 4 × 4 × 4. Exponents are a shorthand way of representing repeated multiplication, and they appear extensively in various mathematical fields, including algebra, calculus, and number theory. Grasping the concept of exponents is crucial for simplifying and solving more complex expressions and equations. For instance, exponents play a significant role in scientific notation, where very large or very small numbers are represented in a compact form. They are also vital in understanding exponential growth and decay, which are fundamental concepts in physics, biology, and economics. Understanding exponents is not just about performing calculations; it's about building a foundational understanding of mathematical notation and its applications across different disciplines. The versatility of exponents makes them an indispensable tool in mathematical problem-solving.

Now that we understand the concept of exponents, let's calculate 4^3. As we established, 4^3 means 4 multiplied by itself three times: 4 × 4 × 4. First, we multiply 4 by 4, which gives us 16. Then, we multiply this result (16) by 4 again. So, 16 × 4 equals 64. Therefore, 4^3 equals 64. This calculation demonstrates the straightforward process of evaluating exponents, and it’s a foundational step in solving more complex mathematical expressions. The ability to quickly and accurately calculate exponents is essential for various mathematical tasks, from simplifying algebraic expressions to solving exponential equations. Moreover, understanding how exponents work is crucial for grasping more advanced concepts such as logarithms and exponential functions. Practice with exponent calculations helps build confidence and fluency in mathematical manipulations. The process of calculating 4^3 not only provides a numerical result but also reinforces the fundamental definition of exponents, making it a valuable exercise in mathematical understanding.

Having calculated 4^3 to be 64, we can now focus on the entire expression: 4^3 / 3. This expression represents the division of 4^3 by 3, which translates to dividing 64 by 3. To perform this division, we can set up the problem as 64 ÷ 3. The division operation is a core arithmetic function, and understanding how to perform it accurately is crucial for solving a wide range of mathematical problems. In this case, we are dividing a whole number (64) by another whole number (3), which will result in a quotient and possibly a remainder. The expression 4^3 / 3 exemplifies the combination of exponents and division, highlighting the importance of following the correct order of operations. Such expressions are commonly encountered in various mathematical contexts, including algebra, calculus, and practical applications in science and engineering. Mastering the evaluation of these expressions is a fundamental skill for anyone pursuing studies in these fields. The ability to seamlessly navigate between different mathematical operations is key to problem-solving proficiency.

To perform the division 64 ÷ 3, we can use long division or a calculator. When we divide 64 by 3, we find that 3 goes into 6 two times (2 × 3 = 6), leaving no remainder. Then, we bring down the 4, and 3 goes into 4 one time (1 × 3 = 3), leaving a remainder of 1. Thus, 64 divided by 3 gives us a quotient of 21 with a remainder of 1. We can express this result as a mixed number or a decimal. As a mixed number, it is 21 1/3. To convert it to a decimal, we divide the remainder (1) by the divisor (3), which gives us approximately 0.333. Therefore, as a decimal, 64 ÷ 3 is approximately 21.333. The process of division is a fundamental arithmetic operation, and proficiency in performing it is essential for various mathematical calculations. Whether using long division or a calculator, understanding the steps involved ensures accuracy in the result. The division of 64 by 3 not only gives us a numerical answer but also illustrates the concept of remainders and the representation of results as mixed numbers or decimals.

As mentioned earlier, the result of 64 ÷ 3 can be expressed as a mixed number. A mixed number consists of a whole number part and a fractional part. From our division, we found that 64 divided by 3 gives us a quotient of 21 with a remainder of 1. This means that 3 goes into 64 twenty-one whole times, with 1 left over. To express this as a mixed number, we write the whole number part (21) and then the fractional part, which is the remainder (1) over the divisor (3). Thus, the mixed number is 21 1/3. Mixed numbers are often used to represent amounts that are more than one whole unit but not quite another whole unit. They provide a clear and intuitive way to understand the quantity, especially in practical applications. For instance, if we have 64 apples and want to divide them equally among 3 people, each person would get 21 whole apples and one-third of an apple. The representation of the result as a mixed number highlights the significance of fractions in expressing parts of a whole. Understanding mixed numbers is crucial for various mathematical operations, including addition, subtraction, multiplication, and division.

Another way to represent the result of 64 ÷ 3 is in decimal form. To convert the fraction 1/3 to a decimal, we divide the numerator (1) by the denominator (3). This division yields a repeating decimal, approximately 0.333. Adding this decimal to the whole number part of our result (21), we get 21.333. This decimal representation provides a concise way to express the quantity, particularly in contexts where decimal notation is preferred or required. Decimal numbers are widely used in various fields, including science, engineering, finance, and everyday calculations. They allow for precise measurements and calculations and are easily manipulated using calculators and computers. The conversion of fractions to decimals is a fundamental skill in mathematics, enabling seamless transitions between different forms of numerical representation. Understanding decimal notation is essential for interpreting and working with data in various formats. The decimal representation of 64 ÷ 3 not only provides a numerical value but also demonstrates the link between fractions and decimals, reinforcing the broader concept of numerical equivalence.

In summary, after evaluating the expression 4^3 / 3, we found that 4^3 equals 64. Dividing 64 by 3 gives us 21 with a remainder of 1. This result can be expressed as a mixed number, 21 1/3, or as a decimal, approximately 21.333. Both forms represent the same value and are commonly used in mathematics and various real-world applications. The process of evaluating this expression has involved several fundamental mathematical concepts, including exponents, division, mixed numbers, and decimal representation. Understanding these concepts is crucial for developing a strong foundation in mathematics and for tackling more complex problems. The ability to seamlessly perform these calculations demonstrates proficiency in arithmetic and an understanding of numerical relationships. Whether expressed as a mixed number or a decimal, the final result of 4^3 / 3 is a testament to the interconnectedness of different mathematical concepts and their application in problem-solving.

In conclusion, evaluating the expression 4^3 / 3 demonstrates the practical application of basic mathematical principles. We began by understanding the meaning of exponents, calculating 4^3 to be 64. We then divided 64 by 3, which resulted in 21 with a remainder of 1. This result was expressed both as a mixed number (21 1/3) and as a decimal (approximately 21.333), highlighting the different ways to represent the same numerical value. This exercise reinforces the importance of understanding exponents, division, and the conversion between fractions and decimals. These skills are fundamental to further mathematical studies and have wide-ranging applications in various fields. The process of evaluating such expressions not only provides a numerical answer but also enhances problem-solving abilities and mathematical fluency.
