Question

simplify.
rewrite the expression in the form $b^n$.
$\frac{b^{-2}}{b^4} = \square$

Explanation:

Step1: Apply exponent division rule

When dividing like bases, subtract exponents: $\frac{b^m}{b^n}=b^{m-n}$

Step2: Substitute exponents and calculate

$m=-2$, $n=4$, so $b^{-2-4}=b^{-6}$

Answer:

$b^{-6}$
