Introduction

In mathematics, the concept of exponents and powers is crucial for solving various problems. When dealing with expressions involving exponents, it's essential to understand the rules and properties that govern their behavior. In this article, we will delve into the product of 7 x square and 7 x cube, exploring the mathematical principles that govern this operation.

What are Exponents and Powers?

Exponents and powers are mathematical operations that involve raising a number to a certain power or exponent. The exponent is a small number that is written to the upper right of the base number, indicating how many times the base number should be multiplied by itself. For example, in the expression 2^3, the exponent 3 indicates that the base number 2 should be multiplied by itself three times: 2^3 = 2 * 2 * 2 = 8.

Understanding the Product of 7 x Square and 7 x Cube

The product of 7 x square and 7 x cube can be expressed as (7^2) * (7^3). To evaluate this expression, we need to apply the rule of exponents that states when multiplying two numbers with the same base, we add their exponents. In this case, the base is 7, and the exponents are 2 and 3.

Applying the Rule of Exponents

Using the rule of exponents, we can simplify the expression (7^2) * (7^3) as follows:

(7^2) * (7^3) = 7^(2+3) = 7^5

Evaluating the Expression

Now that we have simplified the expression to 7^5, we can evaluate it by multiplying 7 by itself five times:

7^5 = 7 * 7 * 7 * 7 * 7 = 16807

Conclusion

In conclusion, the product of 7 x square and 7 x cube is 16807. This result is obtained by applying the rule of exponents, which states that when multiplying two numbers with the same base, we add their exponents. Understanding this rule is essential for solving various mathematical problems involving exponents and powers.
