You can put this solution on YOUR website!
By the Pythagorean theorem, \"r+=+sqrt%28a%5E2+%2B+b%5E2%29\". If you are trying to enter it on an online class/test, you might want to try\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sqrt(a^2 + b^2)
\n" ); document.write( "Sqrt[a^2 + b^2] if you are using Wolfram Mathematica (or similar) software
\n" ); document.write( "$\sqrt{a^2 + b^2}$ if you are using LaTeX\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If it doesn't accept any of these formats, you might want to look into your online software's manual on how to input such expressions.
\n" ); document.write( "
\n" );
