Use the product rule to simplify the expression. Write the result using exponents.
-$w ^ { 5 } \cdot w ^ { 8 } \cdot w ^ { 8 }$
A) $w^{ 48}$
B) ${ } _ { w } 16$
C) $w ^ { 13 }$
D) $w ^ { 21 }$

Quizplus · Accepted Answer

When multiplying powers with the same base, you add the exponents. So, $w^5 \cdot w^8 \cdot w^8 = w^{5+8+8} = w^{21}$.
