How many zeros are at the end of 459 · 885? explain how you can answer this question without actually computing the number. (hint: 10 = 2 · 5.) when this number is written in ordinary decimal form, each 0 at its end comes from a factor of , or one factor of 2 and one factor of . since there are factors of 2 and factors of 5, there are exactly factors of 10 in the number. this implies that the number ends with zeroes.
