Question

Which of the following is/are rationalizing factor for $\sqrt{3}$?

• A. $-\sqrt{3}$
• B. $2\sqrt{3}$
• C. $\sqrt{5}$
• D. $\sqrt{2}$

Answer 1

Answer: (A), (B)

The correct options are
A

$-\sqrt{3}$

B

$2\sqrt{3}$

$Rationalizingfactor\times Surd=Rationalnumber$

Given surd is $\sqrt{3}$. On multiplying $\sqrt{3}$ with $-\sqrt{3}$ and $2\sqrt{3}$, the result will be a rational number.

So, $-\sqrt{3}$ and $2\sqrt{3}$ are rationalizing factors for $\sqrt{3}$.
