Explanation:

Step1: Simplify \(1\times10^{0}\)

Any non - zero number to the power of 0 is 1, so \(1\times10^{0}=1\times1 = 1\).

Step2: Multiply 39 by the result

\(39\times(1\times10^{0})=39\times1 = 39\).

Step3: Convert 39 to scientific notation

Scientific notation is in the form \(a\times10^{n}\) where \(1\leqslant|a|\lt10\) and \(n\) is an integer. We can write 39 as \(3.9\times10^{1}\) because \(3.9\times10 = 39\).

Answer:

\(3.9\times10^{1}\)
