Best ResponseYou've already chosen the best response.1square root property so you should take square root both sides to cancel out the square

Best ResponseYou've already chosen the best response.1square root and square cancel each other out bec you can convert square root to 1/2 exponent \[\huge\rm\sqrt{x}=x^\frac{ 1 }{ 2 }\] so when you take square \[(x^\frac{ 1 }{ 2 })^2\] both 2 cancels out then you have left with just x so that's why we should take square root to cancel out square and square to cancel out the square root
