Radical with x^4 help ?!?

Question

I remembered how to do it in class, but all of a sudden I'm just confusing myself.

ok, here it is: (radical of) 12x^4

would that be 2x(radical 3x^2) ?

I am just not getting the x really.

Answer 1

just remember square root means two inside, come out as one.

you've got √(2)(2)3)(xxxx)

= 2x²√3

see, you can also think of √x^4 as √x²√x² = xx = x²

that's it! ;)

Answer 2

Wow, when I was in school we had to figure this stuff out for ourselves.
