Question

write $2.573 \times 10^{-6}$ in standard notation.

Explanation:

Step1: Recall scientific notation rule

For \(a\times10^{-n}\) (where \(n>0\)), move the decimal point in \(a\) to the left \(n\) times.
Here, \(a = 2.573\) and \(n = 6\).

Step2: Move the decimal point

Start with \(2.573\). Moving the decimal point 6 places to the left: first, we have \(0.2573\) (1 place), \(0.02573\) (2), \(0.002573\) (3), \(0.0002573\) (4), \(0.00002573\) (5), \(0.000002573\) (6).

Answer:

\(0.000002573\)
