Show work please.
Need help.

Answer 1

I got A.

16 times 4 is 64. The square root of 64 is 8.

Answer choice A: The square root of 16 (which is 4) times the square root of 4 ( which is 2)

4 times 2 is 8.

Therefore, I got A.

Answer 2

Option A

Explanation:

`√(16 \cdot 4)`

16 is multiplied with 4 inside the square root . So we can break the square root and make square root seprately

`√(16 \cdot 4)=√(16) \cdot √(4)`

`√(16) =4 \ and \ √(4) =2`

4 times 2 is 8. So 32 is not possible

`√(16 \cdot 4) = √(64) =8`, So only 64 is not equal

We cannot divide the terms because 16 and 4 are in multiplication

Option A is correct
