Question

the length of a bacterial cell is 4.2 x 10^-6 m. express the length of the cell in standard form. the length of the cell is m.

Explanation:

Step1: Recall standard - form definition

The standard form of a number is \(a\times10^{n}\), where \(1\leqslant|a|\lt10\) and \(n\) is an integer. For the number \(4.2\times 10^{-6}\), \(a = 4.2\) and \(n=-6\).

Answer:

\(0.0000042\)
