You can put this solution on YOUR website!
Let us write it this way...looking for n such that
\n" ); document.write( "n^4 = 81(x^12)(y^8)(z^16)
\n" ); document.write( "well we need to raise both sides to the 1/4 power, so that
\n" ); document.write( "n = ±3(x^3)(y^2)(z^4)
\n" ); document.write( "
\n" );
