Question

The conjugate surd of $2-\sqrt{3}$ is ..................

• A. $-2-\sqrt{3}$
• B. $2-(-\sqrt{3})$
• C. $3+\sqrt{2}$
• D. $\frac{1}{2-\sqrt{3}}$

Answer 1

Answer: (B)

$2-(-\sqrt{3})$

The conjugate surd of $2-\sqrt{3}$

$=\left(\overline{2-\sqrt{3}}\right)$

$=2+\sqrt{3}=2-(-\sqrt{3})$

Hence, option B is correct.
