Identify the incorrect relationship(s) from the list below: i. \(\sqrt{7}+\sqrt{3}=\sqrt{6}+\sqrt{4}\) ii. \(\sqrt{7}+\sqrt{3}<\sqrt{6}+\sqrt{4}\) iii. \(\sqrt{7}+\sqrt{3}>\sqrt{6}+\sqrt{4}\)

  1. i
  2. ii
  3. i and iii
  4. ii and iii

Correct answer: i and iii

Solution

\(\sqrt{7}+\sqrt{3}\approx 2.646+1.732=4.378\) and \(\sqrt{6}+\sqrt{4}\approx 2.449+2=4.449\). So the first statement is false, the second is true, and the third is false.
