Question

question 15 of 25 which of the following is the number 0.02204 written in scientific notation? a. 2.240×10⁻³ b. 2.204×10⁻¹ c. 2.204×10⁻² d. 2.204×10²

Explanation:

Step1: Recall scientific - notation form

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

Step2: Move the decimal point

For the number $0.02204$, move the decimal point two places to the right to get $a = 2.204$. Since we moved the decimal point two places to the right, $n=- 2$. So $0.02204 = 2.204\times10^{-2}$.

Answer:

C. $2.204\times10^{-2}$
