Rationalization is the process of removing the imaginary numbers from the denominator of an algebraic expression. It is the method of moving the radical (i.e., square root or cube root) from the bottom (denominator) of the fraction to the top (numerator). To remove the radicals, multiply both the numerator and denominator by the conjugate of the denominator.
Standard Form
The standard form to represent the rationalization of a denominator is given as follows:
Consider a fractional number, 1/(a-√b)
The rationalized form of the number is written as
[1/(a-√b)] × [(a+√b) / (a+√b)]Rationalized Form= [(a+√b) / (a2 -b)
