${(2 e^{- 2})}^{- 4}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

${(2 \frac{1}{e^{2}})}^{- 4}$

Step 2

Combine $2$ and $\frac{1}{e^{2}}$ .

${(\frac{2}{e^{2}})}^{- 4}$

Step 3

Change the sign of the exponent by rewriting the base as its reciprocal.

${(\frac{e^{2}}{2})}^{4}$

Step 4

Apply the product rule to $\frac{e^{2}}{2}$ .

$\frac{{(e^{2})}^{4}}{2^{4}}$

Step 5

Multiply the exponents in ${(e^{2})}^{4}$ .
