simplify 4/y^-3\r
\n" ); document.write( "\n" ); document.write( "multiply the numerator and denominator by y^3\r
\n" ); document.write( "\n" ); document.write( "(4*y^3) / (y^3 * y^-3)\r
\n" ); document.write( "\n" ); document.write( "the denominator becomes y^3-3 = y^0 = 1
\n" ); document.write( "and we are left with
\n" ); document.write( "4*y^3
\n" ); document.write( "
