Step 1: A power of 10 is written as 10k=1 followed by k zeros.
For k=112, 10112 is 1 followed by 112 zeros.
Step 2: The total number of digits is the digit 1 plus the 112 zeros.
1+112=113
Alternatively, using the formula for the number of digits d in n>0:
d=⌊log10n⌋+1
Substitute n=10112:
log10(10112)=112
⌊112⌋+1=112+1=113
10^{112} has 113 digits.
113
