Understanding the Problem

When dealing with exponents, it's essential to understand the rules that govern their behavior. In this case, we're given the expression $\frac{b^8}{b^2}$ and asked to simplify it into the form $b^n$ . To do this, we need to apply the rules of exponents, specifically the quotient of powers rule.

The Quotient of Powers Rule

The quotient of powers rule states that when we divide two powers with the same base, we subtract the exponents. In other words, $\frac{a^m}{a^n} = a^{m-n}$ . This rule is crucial in simplifying expressions involving exponents.

Applying the Quotient of Powers Rule

Now, let's apply the quotient of powers rule to the given expression $\frac{b^8}{b^2}$ . We can rewrite this expression as $b^{8-2}$ , which simplifies to $b^6$ .

Simplifying the Expression

By applying the quotient of powers rule, we have successfully simplified the expression $\frac{b^8}{b^2}$ into the form $b^6$ . This is the final answer.

Example

To illustrate this concept further, let's consider an example. Suppose we have the expression $\frac{x^5}{x^3}$ . Using the quotient of powers rule, we can simplify this expression as follows:
