To raise an exponential expression to a power, keep the base and multiply the exponents

Explanation

For any number \(x\) and any natural numbers \(m\) and \(n\)

$\left(x^m\right)^n = x^{m \cdot n} = x^{mn}$

You read as "the quantity of x to the mth power raised to the nth power equals x to the mnth power."
