\n" ); document.write( "\n" ); document.write( "but $\"12%2Fsqrt%283%29\"$ ? We could do it, but remember $\"sqrt%283%29\"$ is an INFINITE number, that never ends. Hence, we would have to approximate it to sat 10 decimal places and divide by that. It is usually better and simpler to rationalise the denominator, leaving the root on the numerator.\r
