${| - 8^{- 2} |}^{- 1}$

Step 1

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

${| - \frac{1}{8^{2}} |}^{- 1}$

Step 2

Raise $8$ to the power of $2$ .

${| - \frac{1}{64} |}^{- 1}$

Step 3

$- \frac{1}{64}$ is approximately $- 0.015625$ which is negative so negate $- \frac{1}{64}$ and remove the absolute value

${(\frac{1}{64})}^{- 1}$

Step 4

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

$64$
