Solution

The number of digits in a number can be found using the formula log10(n) + 1, rounded down to the nearest whole number.

Given that log 2 = 0.30103, we can use this to find the number of digits in 2^64.

First, we find the log of 2^64. Using the property of logarithms that log(a^b) = b * log(a), we find that log(2^64) = 64 * log(2) = 64 * 0.30103 = 19.26592.

Then, we add 1 to this result and round down to the nearest whole number: floor(19.26592 + 1) = floor(20.26592) = 20.

So, the number of digits in 2^64 is 20.
