Question

what number belongs under the radical

Answer 1

\[16=8x \sqrt{}\]

Answer 2

Do you know what x is?

Answer 3

no

Answer 4

is x supposed to be under the radical? Or do you have two unknowns?

Answer 5

\[A.2 B,4 C,8 D,16\]

Answer 6

so if x is supposed to be under the radical, in which case you're solving for x (which given your answer choices is what I think you have to do)
start by dividing both sides of the equations by 8
16 = 8*sqrt(x)
2 = sqrt(x)

now you can square both sides to eliminate the radical on the right side

2^2 = sqrt(x) ^ 2

x = 4
