Answer 2

Given:

log₁₀(49) = 1.6902

To find:

The number of digits in (49)⁵³

Calculation:

The given number is (49)⁵³

Taking log for the number

=>  log₁₀(49)⁵³ = 53 × log₁₀(49)

By substituting [log₁₀(49) = 1.6902], we get

=>  53 × log₁₀(49) = 53 × 1.6902        

                             = 89.5806

                             ≈ 90

The number of digits in (49)⁵³ is 90
