Question

evaluate.
$(-9)^3 = \square$
$(-5)^2 = \square$

Explanation:

Step1: Expand $(-9)^3$

$(-9)^3 = (-9) \times (-9) \times (-9)$

Step2: Calculate the product

$(-9) \times (-9) = 81$; $81 \times (-9) = -729$

Step3: Expand $(-5)^2$

$(-5)^2 = (-5) \times (-5)$

Step4: Calculate the product

$(-5) \times (-5) = 25$

Answer:

$(-9)^3 = -729$
$(-5)^2 = 25$
