Question

The simplest rationalising factor of $\sqrt[3]{500}$ is

(a) $\sqrt[3]{2}$

(b) $\sqrt[3]{5}$

(c) $\sqrt{3}$

(d) none of these

Answer 1

Given that:.To find simplest rationalizing factor of the given expression we will factorize it as

The rationalizing factor of is, since when we multiply given expression with this factor we get rid of irrational term.

Therefore, rationalizing factor of the given expression is

Hence correct option is.
