Answer 2

Ooh i'l just add √9+7 which = √16 and then simplifies to 8 Thx:)

Answer 3

the square root of 16 isn't 8

Answer 4

I mean 4 cuz 2*8=16 and simplify the square root of 8 and =4

Answer 5

haha there you go

Answer 6

but actually the square root of 16 is 4 because when you set 4^2, you get 16. 8*2 does not equal a square root. A square is when you multiply two of the same numbers
