Okay, I stumbled upon a question that eventually led to this, can someone please help me out? Thank you.

\(\sqrt (160-64\sqrt3)\)

What do you want to do with this expression?

if you want to square

sqrt ( 160 - 64 sqrt 3) you will get 160 - 64 sqrt 3

I also ask, what do you want to do with it?

\(\sqrt{160-64\sqrt3}\\ =4\sqrt{10-4\sqrt3}\)

:< It was part of a problem, but I guess I did the first part wrong. Oof.
