Question

If \(\sqrt{4624}=68\), then the value of:

\(\sqrt{46.24}+\sqrt{0.4624}+\sqrt{0.004624}\)

1. 7.548
2. 7.854
3. 7.458
4. 7.648

Answer 1

Correct Answer - Option 1 : 7.548

Given:

√4624 = 68

Calculation:

⇒ ? = \(√{46.24}+√{0.4624}+√{0.004624}\)

⇒ ? = √(4624 × 10^-2) + √(4624 × 10^-4) + √(4624 × 10^-6)

⇒ 68/10 + 68/100 + 68/1000

⇒ ? = 6.8 + 0.68 + 0.068

∴ ? = 7.548
