-$\sqrt { y ^ { 9 } }$
A) $y ^ { 8 } \sqrt { y }$
B) $y ^ { 4 } \sqrt { y }$
C) $\sqrt { \mathrm { y } ^ { 9 } }$
D) $y \sqrt { y ^ { 7 } }$

Question

Quizplus · Accepted Answer

The expression $\sqrt{y^9}$ simplifies to $y^{\frac{9}{2}}$, which can be further simplified to $y^4 \sqrt{y}$ because $y^{\frac{9}{2}} = y^{4 + \frac{1}{2}} = y^4 \cdot y^{\frac{1}{2}}$.
