Rationalizing the Denominator: A Guide to Simplifying Fraction Formulas

Rationalizing the denominator is a process of simplifying a fraction by eliminating any radicals or irrational numbers in the denominator. This is achieved by multiplying the numerator and denominator by an appropriate value, which is determined by the radical in the denominator. For example, if we have the fraction 1/√2, we can rationalize the denominator by multiplying the numerator and denominator by √2.
