Answer 3

how would you cancel square root ???

Answer 4

I believe the 4x would turn into a 2x but then i wouldnt know what to do with the 13

Answer 5

x have an exponent which is one so you can't take square root of that
to cancel out square root you should take square both side

Answer 6

can you show me? :) please sorry

Answer 7

that's how you should take square both side
remember exponent rules!!
you can change square root to exponent \[\large\rm \sqrt{x} = x^\frac{ 1 }{ 2 }\]
so when you multiply that by 2 both 2/2 can cancel out
