In order to determine the number of zeros defined by 1 googol multiplied by 100 let's look at a simmpler idea.

1 x 100 (2 zeros) = 100 (2 zeros)

`10` (1 zero) x `100` (2 zeros) =` 1,000` (3 zeros)

`100 *100 = 10,000` (4 zeros)

Notice that the number of zeros in the product will be the sum of the number of zeros in the factors.

1000 x 1000 = 1,000,000 (6 zeros)

Therefore googol (100 zeros) multiplied by 100 would have 102 zeros.
