Question

the length of a bacterial cell is 2.3×10^(-6) m. express the length of the cell in standard form. the length of the cell is □ m.

Explanation:

Step1: Recall scientific - notation rule

For a number in scientific notation $a\times10^{n}$, when $n\lt0$, we move the decimal point $|n|$ places to the left. Here $a = 2.3$ and $n=-6$.

Step2: Move the decimal point

Starting with 2.3, since $n = - 6$, we move the decimal point 6 places to the left. We add 5 zeros as place - holders. So $2.3\times10^{-6}=0.0000023$.

Answer:

$0.0000023$
