Question

evaluate. write your a
$8^{-3} = \square$

Explanation:

Step1: Apply negative exponent rule

Recall that $a^{-n} = \frac{1}{a^n}$, so $8^{-3} = \frac{1}{8^3}$

Step2: Calculate denominator

$8^3 = 8 \times 8 \times 8 = 512$

Step3: Simplify to final fraction

$\frac{1}{8^3} = \frac{1}{512}$

Answer:

$\frac{1}{512}$
