Question

The standard form of \(\frac{622}{100,00,00,000}\) is ………………… 

A) 622 × 10 

B) 6.22 × 10 

C) 266 × 10 

D) 6.22 × 10

Answer 1

Correct option is (B) 6.22 x 10^-7

\(\frac{622}{100,00,00,000}=\frac{622}{10^9}=\frac{6.22\times10^2}{10^9}\) \(=6.22\times10^{2}\times10^{-9}\)

\(=6.22\times10^{2-9}\)

= \(6.22\times10^{-7}\)

Answer 2

B) 6.22 × 10^-7
