Simplify. (Assume all variables are nonzero.)
-$\frac { a ^ { 9 } b ^ { 7 } } { a ^ { 3 } b }$
A) $( a b ) ^ { 19 }$
B) $a ^ { 6 } b ^ { 6 }$
C) $a ^ { 27 } b ^ { 7 }$
D) 21

Question

Quizplus · Accepted Answer

When multiplying like bases, you add the exponents. So simplifying the expression, we get:
$$\frac { a ^ { 9 } b ^ { 7 } } { a ^ { 3 } b } = a ^ {9-3}b^{7-1}=a^6b^6$$
Therefore, the answer is choice B.
