You can put this solution on YOUR website!
6/y^3 is the same as 6*y^(-3)
\n" ); document.write( "in general:
\n" ); document.write( "x^(-a) = 1 / x^a
\n" ); document.write( "1 / x^(-1) = x^a
\n" ); document.write( "the variable becomes it's reciprocal and the exponent changes it's sign.
\n" ); document.write( "some examples:
\n" ); document.write( "5^2 = 25
\n" ); document.write( "5^(-2) = 1/25
\n" ); document.write( "1/5^2 = 1/25
\n" ); document.write( "1/5^(-2) = 25
\n" ); document.write( "you can use your calculator to confirm.
