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 plus 15" is a notation used in scientific and mathematical contexts to represent the number 1 followed by 15 zeros, which is equal to 1,000,000,000,000,000, or one quadrillion. The "e" stands for "exponent," indicating that 1 should be multiplied by 10 raised to the power of 15. This format is often used for ease of reading and writing very large or very small numbers.
1e-17 = -16
1x10153 times 999999999 is 999999999x10153. Normalizing that, you get 9.999999999x10161.
