Question

write the expression as a single power.
$(-6)^5 \cdot (-6)^4 =$ ?
$6^9$
$6^{20}$
$(-6)^9$
$(-6)^{20}$

Explanation:

Step1: Apply exponent product rule

When multiplying powers with the same base, add exponents: $a^m \cdot a^n = a^{m+n}$

Step2: Substitute values and calculate

$(-6)^5 \cdot (-6)^4 = (-6)^{5+4} = (-6)^9$

Answer:

$(-6)^9$
