-$\left( 9 x ^ { - 2 } \right) \left( 8 x ^ { - 6 } \right)$
A) $- 72 x ^ { 12 }$
B) $72 x ^ { 12 }$
C) $\frac { 72 } { x ^ { 8 } }$
D) $72 x ^ { 8 }$

Question

Quizplus · Accepted Answer

When multiplying powers with the same base, you add the exponents. Thus, $9x^{-2} \times 8x^{-6} = 72x^{-2-6} = 72x^{-8}$. To write without negative exponents, it becomes $\frac{72}{x^8}$.

Simplify the Expression and Write the Answer Without Negative Exponents (9x−2)(8x−6)\left( 9 x ^ { - 2 } \right) \left( 8 x ^ { - 6 } \right)(9x−2)(8x−6)
