how would you cancel  square root ???

elisaneedshelp · Answer

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

nnesha · Answer

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

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
