# Factoring Exponentials

An exponential expression typically looks like this: a^b, where ‘a’ is the base, and ‘b’ is the exponent. It represents the repeated Multiplication in Algebraic Expressions of ‘a’ by itself ‘b’ times.

In this article, we will discuss the process of factoring exponentials, and provide solved examples.

**Factoring Exponents**

Factoring exponentials involves expressing them as a product of simpler exponential expressions. To do this, we need to find common factors in the terms and simplify.

**Example **

Factor the expression 2^3 * 2^4.

Here, we have two terms with the same base (2). We can add the exponents to simplify: 2^(3+4) = 2^7.

So, 2^3 * 2^4 = 2^7.

**Factoring Exponentials with Different Bases**

Sometimes, you might encounter exponentials with different bases. In such cases, you can factor them by recognizing common factors and simplifying them.

**Example **

Factor the expression 3^2 * 2^2.

Here, we can’t combine the bases, but we can simplify each term individually:

3^2 * 2^2 = 9 * 4 = 36.

So, 3^2 * 2^2 = 36.

**Factoring Exponentials with Negative Exponents**

Negative exponents might seem tricky, but they follow a straightforward rule:

a^(-b) = 1 / (a^b)

We use this rule to factor exponentials with negative exponents.

**Example **

Factor the expression 4^(-2).

Apply the rule:

4^(-2) = 1 / 4^2 = 1 / 16.

So, 4^(-2) = 1/16.

**Factoring Exponentials with Variables**

Factoring exponentials with variables is a bit more complex, but it follows similar principles. You factor by finding common bases and simplifying the exponents.

**Example **

Factor the expression x^2 * x^3.

Here, both terms have the same base (x), so we can add the exponents:

x^(2+3) = x^5.

So, x^2 * x^3 = x^5.
