Simplify the radical expression. Assume all variables represent positive real numbers.
-$\sqrt { 36 y ^ { 18 } }$
A) $6 y ^ { 18 }$
B) $36 \mathrm { y } ^ { 9 }$
C) $6 y ^ { 9 }$
D) $6 y ^ { 16 }$

Question

Quizplus · Accepted Answer

The expression $\sqrt { 36 y ^ { 18 } }$ simplifies to $6 y ^ { 9 }$ because the square root of 36 is 6, and the square root of $y^{18}$ is $y^9$ (since $\sqrt{y^{2n}} = y^n$ for any positive integer n).
