Rationalization (mathematics)

the process of removing a square root or imaginary number from the denominator of a fraction

The rationalization of denominators is to get rid of radicals that are in the denominator[1] (the bottom part of a fraction). It works by dividing the bottom radical by itself, then multiplying that by the first expression.
