the answer is 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000. This is basically 101 zeros. The reason for that is because since 10^100 already has 100 zeros, multiplying it by one more will give it one more zero making it 101 zeros.
However, if you want it in an exponent form the answer is 10^101 I believe.
