Question

Simplify the radical:

Answer 1

First you need to recall that any square under the radical "cancels" and can be moved out front. So an example would be \(\sqrt{12}\) can be written as \(\sqrt{4*3}\) and the 4 can be restated as \(\sqrt{2^2*3}\) allowing the square and root on the 2 to "cancel" and pull the 2 out front for a final solution of \(2\sqrt{3}\)
The same logic applies here.

Answer 2

It can be easier to see if you list the number under the radical in its prime factors.

Answer 3

okay that helped a lot and normaly it take me a min to understand it! ha thanks
