Introduction

Exponential form is a powerful way to represent mathematical expressions, making it easier to perform calculations and understand complex concepts. In this article, we will delve into the world of exponential form, exploring its definition, properties, and applications. We will also examine a specific example, $\frac{1}{(a)(a)(a)(a)(a)(a)}$ , and determine its equivalent expression in exponential form.

What is Exponential Form?

Exponential form is a mathematical notation that represents a number or expression as a power of a base. It is denoted by the symbol $a^b$ , where $a$ is the base and $b$ is the exponent. The base can be any real number, and the exponent can be any integer or rational number.

Properties of Exponential Form

Exponential form has several properties that make it a useful tool in mathematics. Some of the key properties include:

Product of Powers: When multiplying two exponential expressions with the same base, we add the exponents. For example, $a^m \cdot a^n = a^{m+n}$ .
Power of a Power: When raising an exponential expression to a power, we multiply the exponents. For example, $(a^m)^n = a^{mn}$ .
Zero Exponent: Any non-zero number raised to the power of zero is equal to 1. For example, $a^0 = 1$ .
Negative Exponent: A negative exponent can be rewritten as a positive exponent with a reciprocal base. For example, $a^{-m} = \frac{1}{a^m}$ .

Example: Writing in Exponential Form

Let's examine the expression $\frac{1}{(a)(a)(a)(a)(a)(a)}$ . To write this expression in exponential form, we need to identify the base and the exponent.

Base: The base is $a$ , as it is the variable that is being raised to a power.
Exponent: The exponent is the number of times the base is being multiplied together. In this case, the base is being multiplied together 6 times, so the exponent is 6.

Using the properties of exponential form, we can rewrite the expression as:

\frac{1}{(a)(a)(a)(a)(a)(a)} = a^{-6}

Therefore, the expression in exponential form is $a^{-6}$ .

Conclusion

In conclusion, exponential form is a powerful tool in mathematics that allows us to represent complex expressions in a concise and elegant way. By understanding the properties of exponential form and how to write expressions in this notation, we can perform calculations and solve problems more efficiently.
