y cube root(56x) - cube root(189 x y^3)
\n" ); document.write( "y cube root(8*7x) - cube root(27*7 x y^3)
\n" ); document.write( "y cube root(2^3*7x) - cube root(3^3*7 x y^3)
\n" ); document.write( "pull out 2^3, 3^3 & y^3
\n" ); document.write( "2y cube root(7x) -3y cube root(7x)
\n" ); document.write( "-y cube root(7x) (ans)
