If 1,000 = 1 x 10(3) [one times ten to the 3rd power]
and 1,000,000 = 1 x 10(6) [one times ten to the 6th power]
There would be 100,000,000 (one hundred million pennies in a million dollars) [ $1million x 100 pennies/dollar]
Then counting your zeroes would add up to 8... so...
your answer would be...
1 x 10(8) [one times ten to the 8th power]
OR
1000 000 dollars x (100 pennies / 1dollar) = 100 000 000
its 1x10E8 pennies
