If both numbers are 1 followed by zeros, their product is 1 followed by the sum of the zeros. - Let N be the number of zeros in the first number. - Let M be the number of zeros in the second number. Then: - Product = 1 followed by N+M zeros - Equivalently: Product = 10^(N+M) If you paste the exact counts of zeros (or confirm the total digits of each number), I can give you the explicit decimal or the exact exponent. For example, if the first has N zeros and the second has M zeros, the answer is 1e(N+M) or "1" followed by N+M zeros.
