Question

if \(\sqrt {4036} \) = 64, then the value of \(\sqrt {40.36} \) + \(\sqrt {0.4036} \) + \(\sqrt {0.004036} \) + \(\sqrt {0.00004036} \) will be

1. 7.1216
2. 7.0914
3. 7.1104
4. None of the above

Answer 1

Correct Answer - Option 3 : 7.1104

Calculation:

Given, √4036 = 64

⇒ √40.36 = 6.4 

⇒ √0.4036 = 0.64

⇒ √0.004036 = 0.064

⇒ √0.00004036 = 0.0064

Now,

6.4 + 0.64 + 0.064 + 0.0064 = 7.1104
