Which option helps show that the claim (\sqrt{2}+\sqrt{3}+\sqrt{6}) is rational is false?
Answer and explanation
Correct answer: Roots of different non-perfect squares give independent irrational parts
Step 1: (\sqrt{2}), (\sqrt{3}), and (\sqrt{6}) are linked to different non-perfect squares. Step 2: Their irrational parts do not cancel through ordinary addition, so the sum is not rational. Step 3: Avoid false identities such as (\sqrt{a+b}=\sqrt{a}+\sqrt{b}).
