I am confused with this new way of writing exponential. For example I saw a question where person has changed 1.66X10e-27 to 1.66e-26. I am confused how -27 is reduced to -26 thanks

What do you mean? Do you simply think that there is an error in the solution? (1.66e-27 and 1.66e-26 are two different things) – Mayank Pandey Mar 19 '14 at 05:46

Nope and actually I am confused between 1.66x10e-27 and 1.66e-26 – ZafarYousafi Mar 19 '14 at 05:48

e-27 is a way of expressing $10^{-27}$ in programming. There is no need for a 10 before it; in fact, putting a 10 before it causes it to be multiplied. So 1.66x10e-27 actually means $1.66 \times 10 \times 10^{-27} = 1.66 \times 10^{-26}$, which is equal to 1.66e-26.
