You can put this solution on YOUR website!
first factorize\r
\n" ); document.write( "\n" ); document.write( "78:2=39
\n" ); document.write( "39:3=13
\n" ); document.write( "13:13=1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so we got 2, 3 and 13 factors. if you don't have all the factors with even powers you can not find the exact value of their square root. so let it stay \"sqrt%2878%29\" or \"sqrt%282%29%2Asqrt%283%29%2Asqrt%2813%29\" because there is no way to simplify it.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's way people call the numbers like \"sqrt%2878%29\" irrational numbers because it is impossible to find an answer as a fraction or an integer.
