Explanation:

Step1: Recall scientific - to - standard form rule

For a number in scientific form \(a\times10^{n}\), when \(n\lt0\), we move the decimal point \(|n|\) places to the left. Here \(a = 7.1\) and \(n=- 6\).

Step2: Move the decimal point

Starting with \(7.1\), moving the decimal point 6 places to the left gives \(0.0000071\).

Answer:

\(0.0000071\)
