Answer:
11yz² and when evaluating we get 22528
Explanation:
We have the expression

We know that a square root is a 1/2 exponent, so we're going to multiply the exponents of y and z by 1/2.

Therefore the expression is rewritten as

Now we're going to evaluate this expression for y = 8 and z = 16

Thus, when evaluated the result is 22528
