You can put this solution on YOUR website!
Assume the problem is:\r
\n" ); document.write( "\n" ); document.write( "If $\"y=log%282%2C%28x%2Bsqrt%28x%5E2%2B1%29%29%29\"$ , then $\"2%5Ey+-+2%5E%28-y%29\"$
\n" ); document.write( "We can write $\"2%5Ey+-+2%5E%28-y%29\"$ as $\"2%5Ey+-+1%2F2%5Ey\"$
\n" ); document.write( "the exponent equiv of logs
\n" ); document.write( " $\"2%5Ey=%28x%2Bsqrt%28x%5E2%2B1%29%29\"$ , therefore
\n" ); document.write( ":
\n" ); document.write( " $\"2%5Ey+-+1%2F2%5Ey\"$ = $\"%28x%2Bsqrt%28x%5E2%2B1%29%29\"$ - $\"1%2F%28x%2Bsqrt%28x%5E2%2B1%29%29\"$ ,
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "

\n" );
