-$\frac { y ^ { - 9 } } { y ^ { 2 } }$
A) $\frac { 1 } { y ^ { 7 } }$
B) $\frac { 1 } { y ^ { 11 } }$
C) $y ^ { 11 }$
D) $\frac { 1 } { y ^ { 18 } }$

Question

Quizplus · Accepted Answer

When dividing powers with the same base, subtract the exponents: $y^{-9} / y^2 = y^{-9-2} = y^{-11}$, which simplifies to $\frac{1}{y^{11}}$.
