Simplifying a radical involves finding a factor that is a perfect square and making the radical two radicals, one of which is a perfect square.
\n" ); document.write( "Sqrt(75)=sqrt(25)*sqrt(3)
\n" ); document.write( "That is 5* sqrt(3)
\n" ); document.write( "Yes, I could write sqrt(15)(sqrt(5), but neither of those is a perfect square.
\n" ); document.write( "Try to divide the original radical by perfect squares, beginning with 4, then 9, then 16, 25, 36,...
\n" ); document.write( "Square root of 98= sqrt (49)*sqrt(2)
\n" ); document.write( "That is 7 sqrt(2).
\n" ); document.write( "-------------------
\n" ); document.write( "To rationalize a radical, multiply the denominator's radical by itself and therefore do the same to the numerator.
\n" ); document.write( "5/ sqrt(2)= 5 * sqrt(2)/sqrt(2)*sqrt(2). That makes the denominator an integer but makes the numerator a radical. That's OK. The result is 5 sqrt(2)/2
\n" ); document.write( "
\n" );
