Answer:
y^9

This is the same as saying y^9

===================================================

Step-by-step explanation:

When we apply the square root to the expression
a^(2b), we end up with
a^b


\sqrt{a^(2b)} = a^b

The exponent 2b divides in half to get b

Based on that rule, we can then say:


\sqrt{y^(18)} = y^(18/2) = y^9
