Rationalize the denominator means to take whatever action required so that the denominator of the fraction is a rational number. In this case, multiplication of the denominator by will do the trick nicely. However, you can't just multiply the denominator by something other than 1 and still have the same value for the fraction overall. The only thing you can multiply the whole fraction by is something that has a value of 1. In this case, it will be convenient to multiply the entire fraction by , thus:
Your second problem is trivial because both of the radicands are perfect squares, meaning the square roots are rational.
