Question 1
What is the value of ${√17}/3$ − $2/{√17}$?
${11√17}/51$.
${-11√17}/51$.
${9√17}/51$.
${-9√17}/51$.
Ans: a
The given expression can be simplified to ${{(√17)^2} - 3 × 2}/{3 × √17}$, which is same as ${17 - 6}/{3 × √17}$, which is same as ${11/{3 × √17}$. Rationalizing, we get ${11/{3 × √17} × {√17/√17}$ which gives ${11√17}/51$
