what is e? $$5.87849981x10^{12}x 3.5x10^{8}$$ when i solve this equation, the answer is 2.0574749e+21. what does that mean?
It's a shorthand way for expressing a number without using scientific notation directly....in this case.....
2.0574749e+21 equates to.....
2.0574749 x 1021
P.S. ......This is always confusing to me, too!!!
