How do you rationalise the denominator?
It depends on what the denominator was to start with: a surd or irrational or a complex number. You need to find the conjugate and multiply the numerator by this conjugate as well as the denominator by the conjugate. Since multiplication is by [conjugate over conjugate], which equals 1, the value is not affected. If a and b are rational numbers, then conjugate of sqrt(b) = sqrt(b) conjugate of a + sqrt(b) = a - sqrt(b), and conjugate of a + ib = a - ib where i is the imaginary square root of -1.

What is the comparative form of an adverb?
To find the comparative of an adverb, find its root word. Once you have the root word, conjugate it for more. For example, if you are trying to find the comparative for 'quickly,' first find the root, quick, then conjugate it for more quick: quicker.(If you are asking how to make a comparative adverb, it's just more adverb. For example, more quickly.)
