MCQ
The rationalisation factor of $\sqrt3,$ is:
- A$-\sqrt3$
- B$\frac{1}{\sqrt3}$
- C$2\sqrt3$
- D$-2\sqrt3$
✓
Answer
- $\frac{1}{\sqrt3}$
Solution:
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).
