Question

5.2277 × 10⁻³

Explanation:

Step1: Recall scientific notation to decimal

A number in scientific notation \(a\times10^{n}\) (where \(1\leq|a|\lt10\)): if \(n\) is negative, move the decimal point \(|n|\) places to the left. Here, \(5.2277\times10^{-3}\), \(n = - 3\), so move decimal 3 places left.

Step2: Perform the decimal shift

\(5.2277\times10^{-3}=\frac{5.2277}{10^{3}}=\frac{5.2277}{1000}=0.0052277\)

Answer:

\(0.0052277\)
