Best ResponseYou've already chosen the best response.1The square root and the square cancel because a square root can also be writein the form of \[(b)^{1/2}\] so when you square that you get \[(b)^{\frac{ 1 }{ 2 } . 2}\] and according to index laws the 1/2 and 2 cancel so you just get \[(b)^1 \] which is just (b)
