Question

1. choose the correct scientific notation for the given number. the length of a honeybee is about 0.013 meters. 1.3×10⁻² 1.3×10² 13×10⁻³ 0.13×10⁻²

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 0.013 to scientific notation

Move the decimal point 2 places to the right to get $a = 1.3$. Since we moved the decimal point 2 places to the right, $n=-2$. So, $0.013 = 1.3\times10^{-2}$.

Answer:

A. $1.3\times 10^{-2}$
