Answer
$(m^{-36})^{\frac{1}{3}} = m^{-12}$
Work Step by Step
When we raise a power to a power, we multiply the powers together and keep the base.
We have to think what number multiplied with $\frac{1}{3}$ will give us $-12$:
$\frac{1}{3}x = -12$
Divide each side by $\frac{1}{3}$ to solve:
$x = -36$
Let's rewrite the equation:
$(m^{-36})^{\frac{1}{3}} = m^{-12}$
