Math and science made easy - learn from a retired engineer

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 10^{4} 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

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
