You can put this solution on YOUR website!
You see if you can reduce them to have the same root.
\n" ); document.write( "Example:
\n" ); document.write( " $\"sqrt%285%29%2B5%2Asqrt%2845%29=sqrt%285%29%2B5%2Asqrt%289%2A5%29\"$
\n" ); document.write( " $\"sqrt%285%29%2B5%2Asqrt%2845%29=sqrt%285%29%2B5%2A3%2Asqrt%285%29\"$
\n" ); document.write( " $\"sqrt%285%29%2B5%2Asqrt%2845%29=16%2Asqrt%285%29\"$
\n" ); document.write( "If not then you can make them have the same root by multiplying numerator and denominator by the same number.
\n" ); document.write( "

\n" ); document.write( "

\n" ); document.write( " $\"sqrt%282%29%2Bsqrt%287%29=sqrt%2814%29%281%2Fsqrt%287%29%2B1%2Fsqrt%282%29%29\"$
\n" ); document.write( " $\"sqrt%282%29%2Bsqrt%287%29=sqrt%2814%29%28sqrt%287%29%2F7%2Bsqrt%282%29%2F2%29\"$
\n" ); document.write( "But, as you see, the answer isn't always any simpler. \r
