You can put this solution on YOUR website!
You've done fairly well so far except...
  • You forgot the \"log\" in front of your answer
  • Exponents do not distribute! \"%28x%2B5%29%5E5\" IS NOT \"x%5E5+%2B+5%5E5\"!!! And \"%28x-3%29%5E3\" IS NOT \"x%5E3+-+3%5E3\".

    • \n" ); document.write( "So your answer should be:
    \n" ); document.write( "\"log%28%28%28x%5E2%28x%2B5%29%5E5%29%2F%28x-3%29%5E3%29%29\"
    \n" ); document.write( "or whatever you get if you correctly raise x+5 and x-3 to their respective powers.

    \n" ); document.write( "If you feel you should multiply these out, look into using the binomial theorem. If you do not know how to use the Binomial Theorem, then just multiply (x+5)(x+5)(x+5)(x+5)(x+5) and (x-3)(x-3)(x-3) by hand. \n" ); document.write( "
\n" );
