Answer 1

The product of 40000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 and 100000000000000000000000000000000000000000000000000000 is 4 x 10^154 multiplied by 1 x 10^64. When multiplying numbers in scientific notation, you add the exponents and multiply the coefficients, resulting in 4 x 1 x 10^(154+64) = 4 x 10^218. Therefore, the answer is 4 followed by 217 zeros.

Answer 2

Multiply the first digit of each and then put all the zeros on the end. My suspicion is that you're just being difficult.
