Evaluate 8-2.<br>A. -16<br>B. -64<br>C. -1/64<br>D. 1/64<br>

makvit [3.9K]

I'm assuming you meant to write 8^(-2) or $8^{-2}$ where the -2 is the exponent over the 8.

If my assumption is correct, then we use the rule $a^{-b} = \frac{1}{a^b}$

So,

$a^{-b} = \frac{1}{a^b}\\\\8^{-2} = \frac{1}{8^2}\\\\8^{-2} = \frac{1}{64}$
