Question

If √10 = 3.162, then the value of 1/√10 is 

A) 31.62 

B) 3.162 

C) 0.3162 

D) 316.2

Answer 1

Correct option is (C) 0.3162

\(\because\) \(\sqrt{10}=3.162\)

\(\therefore\) \(\frac1{\sqrt{10}}=\frac{\sqrt{10}}{\sqrt{10}\times\sqrt{10}}=\frac{\sqrt{10}}{10}\) \(=\frac{3.162}{10}=0.3162\)

Answer 2

Correct option is  C) 0.3162
