You've just solved a problem and the answer is the mass of an electron, me=9.11×10−31kilograms. how would you enter this number into the answer box?
enter your answer in kilograms using three significant figures. note that the units are provided for you to the right of the answer box.

The mass of an electron, me, 9.11 × 10⁻³¹ kilograms shows there are 3 important numbers in them, namely numbers 9, 1, and 1

Significant numbers are obtained from measurement results of exact numbers and the last number estimated

This is called significant numbers

the scientific notation can be described as:

a, ... x 10ⁿ

a, ... called a significant number

10ⁿ is called a big order
