### Question 4

What is the value of ${√11}/6$ − $3/{√11}$?

**A**

${-7√11}/66$.

**B**

${+7√11}/66$.

**C**

${-3√11}/66$.

**D**

${+3√11}/66$.

**Soln.**

**Ans: a**

The given expression can be simplified to ${{(√11)^2} - 6 × 3}/{6 × √11}$, which is same as ${11 - 18}/{6 × √11}$, which is same as ${-7/{6 × √11}$. Rationalizing, we get ${-7/{6 × √11} × {√11/√11}$ which gives ${-7√11}/66$

### Question 5
