MCQ
The rationalisation factor of $\sqrt3,$ is:
  • A
    $-\sqrt3$
  • $\frac{1}{\sqrt3}$
  • C
    $2\sqrt3$
  • D
    $-2\sqrt3$

Answer

Correct option: B.
$\frac{1}{\sqrt3}$
Rationalisation factor of any number like $\sqrt{\text{a}}$ is $\frac{1}{\text{a}}$ or $\frac{1}{\text{a}}$ is $\sqrt{\text{a}}.$
So. Rationalisation factor of $\sqrt3$ is $\frac{1}{\sqrt3}.$
Hence, correct option is $(b)$.
