How many pennies equal one million dollars? write your answer in scientific notation.

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
