square root of 128x^3 over the square root of 2xy.
sqrt%28128x%5E3%29%2Fsqrt%282xy%29
we can factor inside the top radical to reveal perfect squares
sqrt%2864%2A2%2Ax%5E2%2Ax%29%2Fsqrt%282xy%29
extract the square roots of those perfect square
8x%2Asqrt%282x%29%2Fsqrt%282xy%29
we can write the denominators as
8x%2Asqrt%282x%29%2F%28sqrt%282x%29%2Asqrt%28y%29%29
we can cancel sqrt%282x%29
%288x%29%2Fsqrt%28y%29
