\frac{ 7}{ \sqrt{2} + \sqrt{5}}
To rationalize the denominator, you must multiply both the numerator and the denominator by the conjugate of the denominator. The most common used irrational numbers that are used are radical numbers, for example √3. Example 1: Rationalize the denominator {5 \over {\sqrt 2 }}.Simplify further, if needed.
