Question

Which expression is equivelant to...?

Answer 1

`8√(2)`

128 can be simplified to 2*2*2*2*2*2*2.

128/16=8

16/8=2 8/2=4

8/2=4 4/2=2

4/2=2

You can make three groups of 2, (2*2) (2*2) (2*2) * 2

So, then you pull those groups out of the square root and multiply them. Thats how you get the 8.
