Number of cyphers after decimal before a significant figure comes in open parentheses 5 over 3 close parentheses to the power of negative 100 end exponent is

In this question, we have to find the number of cyphers. We need to remember that the cypher number can be found from the logarithmic calculation but to find the actual value or to visualize it we need to remove the logarithm. Here, log105 = 0.6990 and log103 = 0.4770.
