WebThe denominator here contains a radical, but that radical is part of a larger expression. To get rid of it, I'll multiply by the conjugate in order to "simplify" this expression. The multiplication of the denominator by its conjugate results in a whole number (okay, a negative, but the point is that there aren't any radicals): WebThe main idea in rationalizing denominators is to multiply the original fraction by an appropriate value so that after simplifying, the denominator no longer contains radicals. When the denominator is a monomial, we can apply the fact that: \sqrt {x} \cdot \sqrt {x}= \sqrt { { {x}^2}}=x x ⋅ x = x2 = x. Therefore, we can multiply both the ...

The idea is to take out the higher power of 'x' in the denominator first. If the x squared is under a radical, take that out so you're left with just 'x'. After this, divide every term by 'x'. Once you are finished with this, you can rewrite the equation.
