Rationalization of the denominator in the radicand
There will be two different cases:
Simple rationalization
.
Multiply the numerator and denominator of the radicand by such a number as will make the denominator a perfect
n
th power (here n = 3) and then remove the denominator from under the radical sign.
Rationalizing binomial denominators
.
To rationalize a fraction whose denominator is a binomial with radicals of index 2, multiply numerator and denominator by the conjugate.
