Question

Could you help me simplify this?
√ = square root symbol

6 √ 2 - 3 √ 2

Answer 1

do 6-3 and leave the square root of 2 there
and you get 3 √2

Answer 2

so you just minus the two numbers and use whatever square root is there?

Answer 3

on one condition\THE NUMBER UNDER THE RADICAL MUST BE THE SAME
if not then you can simplify the radical and if still not you leave it like that
