1e+ is the number of zeros for example 10 is 1e+1 it have only 1 zeros 1eX is the size of the 1e+ example is that 1e+1000 is 1eX3 the number of zeros in 1e+ 1e^ is a large like 1e+10(1e+100000000000) same as the 1eX for the + 1e^1 is 1eX10 or 1e+100billion 1e- 1e/
1 nanometer=1E-09 meters and the answer is .000000672 meters
One microsecond is equal to one millionth (1e-6) of a second).
1e-24 = -23
1e-17 = -16
Beta decay
1x10153 times 999999999 is 999999999x10153. Normalizing that, you get 9.999999999x10161.
