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.
1x10153 times 999999999 is 999999999x10153. Normalizing that, you get 9.999999999x10161.
