Question

Rationalise 2root3 and 5root2

Answer 1

To rationalize a number, you need to multiply the term with the irrational part with the symbol opposite to that of the to be rationalized term . So,

2 \root 3 * root 3\root 3 = 2 root 3 \ 3

5 \root 2 * root 2\root 2 = 5 root 2 \ 2

Hence it is rationalized .
