the diameter of a human blood cell is 0.0000062 m. how can this number best be expressed in scientific notation?
a. 6.2×10^(-6) m
b. 6.2× - 10^6 m
c. 62×10^(-5) m
d. 6.2×10^(-5) m

Explanation:

Step1: Recall scientific - notation rule

Scientific notation is of the form $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Convert 0.0000062 to scientific notation

Move the decimal point 6 places to the right to get a number between 1 and 10. So, $0.0000062 = 6.2\times10^{-6}$.

Answer:

A. $6.2\times 10^{-6}\text{ m}$
