2*2*2*14
2*2*2*2*7
sqrt 112= sqrt(16*7)=4*sqrt7

2. 112 = 4 x 28
sqrt 112 = 2 sqrt 28

If sqrt112 is a multiplier of 1/2, the answer would be sqrt28.

Parentheses would have helped clarify where the sqrt112 goes.

simplify the expression (4 square root of x)/(6-square root of x) I need help with this. I've worked it out to the point where i got (2 square root of x)/(3-square root of x), but I'm pretty sure that it can be simplified further.
