Correct option is (A) 6.324 \(\because\) \(\sqrt{10}\) = 3.162 \(\therefore\) \(\sqrt{40}=\sqrt{4\times10}\) \(=2\sqrt{10}=2\times3.162\) = 6.324

Correct option is (C) 0.3162 \(\because\) \(\sqrt{10}=3.162\) \(\therefore\) \(\frac1{\sqrt{10}}=\frac{\sqrt{10}}{\sqrt{10}\times\sqrt{10}}=\frac{\sqrt{10}}{10}\) \(=\frac{3.162}{10}=0.3162\)
