Question

formulas for cube for rationalising of denominator​

Answer 1

Answer:

When a denominator has a higher root, multiplying by the radicand will not remove the root. Instead, to rationalize the denominator we multiply by a number that will yield a new term that can come out of the root. For example, with a cube root multiply by a number that will give a cubic number such as 8, 27, or 64.

The bottom of a fraction is called the denominator.

But many roots, such as √2 and √3, are irrational.
