Answer: 8y⁸
Step-by-step explanation:
To find the square root of the expression, you want to find the square root of each term.
The square root of 64 is 8. You can write y¹⁶ as (y⁸)². We can pull out this 2 from the square root because it cancels out with the square root. Therefore, the answer is 8y⁸.
