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