Question
Arrange the following in ascending order.$a=\sqrt{2}+\sqrt{11}, b=\sqrt{6}+\sqrt{7}$,$c=\sqrt{3}+\sqrt{10}$ and $d=\sqrt{5}+\sqrt{8}$(A) $a b c d$(B) $a b d c$(C) $a c d b$(D) acbd
Step 1
For $a$, we have $a^2 = (\sqrt{2} + \sqrt{11})^2 = 2 + 11 + 2\sqrt{2}\sqrt{11} = 13 + 2\sqrt{22}$. Show more…
