Just do the same thing as you would normally do. When you square a square root of a number, it cancels out to just the number--if you square the square root of x, the result is x.
\n" ); document.write( "a = 5, b = ?, c = $\"sqrt%2889%29\"$
\n" ); document.write( " $\"a%5E2+%2B+b%5E2+=+c%5E2\"$
\n" ); document.write( " $\"5%5E2+%2B+x%5E2+=+sqrt%2889%29%5E2\"$
\n" ); document.write( " $\"25+%2B+x%5E2+=+89\"$
\n" ); document.write( " $\"x%5E2+=+64\"$
\n" ); document.write( " $\"sqrt%28x%5E2%29+=+sqrt%2864%29\"$
\n" ); document.write( "x = 8
\n" ); document.write( "Therefore, b = 8.
