Question 4
What is the value of ${√11}/6$ − $3/{√11}$?
A
${-7√11}/66$.
B
${+7√11}/66$.
C
${-3√11}/66$.

Soln.
Ans: a
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
What is the value of $√{7 + √1764}$?
