If you were asked to find 1/2 of 140 mm that would be easy, just take 140 times 1/2 and you get 70. Do the same with 105 septillionth.
105 septillionth is 105 x 10-24
105 x 10-24 times 140 = 14700 x 10-24 = 1.47 x 104 x 10-24 = 1.47 x 10-20 mm
Is an answer in mm acceptable or do they want meters? If they want meters, divide by 1000 and the answer becomes 1.47 x 10-23 m

Well, I would say that is a simplified answer but if you want it with no powers, then move the decimal 20 places so then the answer would be 0.0000000000000000000147 mm03/03/19

no they dont want meters. now my question is, if your answer is indeed 1.47 x 10-20 mm than what is that simplified? like 100% numbers no powers or anything, in mm not meters03/03/19
