\n" ); document.write( "This is because $\"a%5E%28-b%29+=+1%2F%28a%5Eb%29\"$
\n" ); document.write( "

\n" ); document.write( "This is becaue $\"%28a%2Fb%29%5Ec+=+%28a%5Ec%29+%2F+%28b%5Ec%29\"$
\n" ); document.write( "

\n" ); document.write( "This is because $\"1%2F%28a%2Fb%29+=+b%2Fa\"$
\n" ); document.write( "

\n" ); document.write( "

\n" ); document.write( "This is because $\"a%5Ec+%2F+b%5Ec+=+%28a%2Fb%29%5Ec\"$
\n" ); document.write( "

\n" ); document.write( "This is because $\"%28a%2Fb%29%2Fc+=+a%2F%28b%2Ac%29\"$
\n" ); document.write( "Now divide top & bottom by $\"y%5E2\"$
\n" ); document.write( " $\"+%28y%5E2+%2F+%28x%5E4%2Ax%2Ay%5E5%29%29%5E2+=+1%2F%28x%5E5%2Ay%5E3%29%5E2+\"$ answer
\n" ); document.write( "-----------------------------------------------------
\n" ); document.write( "There is a quick & easy way to test answer
\n" ); document.write( "I'll say $\"x+=+3\"$ and $\"y+=+7\"$ (I could use any numbers)
\n" ); document.write( " $\"%28+%28x%2Ay%5E5%29+%2F+%28x%5E-4%2Ay%5E2%29+%29%5E-2\"$
