a plant cell is 0.00001267 meter wide. How is this number written in scientific notation?

The answer is 0.00001267 m = 1.267 * 10^ (-5) m. In scientific notation, the number is written as two factors - a number m from 0-10 and 10 raised to the n power: m x 10^n. 0.00001267 m = 1.267 x 0.00001 m. 0.00001 m = (0.1) ^5 = 10^ (-5). So: 0.00001267 m = 1.267 x 0.00001 m = 1.267 x (0.1) ^5 m = 1.267 x 10^ (-5) m.
