1) Calculating that expression:

Let's first multiply the numbers before the power:

2) 3.8 x 9.4 =35.72


\begin{gathered} (3.8\cdot10^3)\cdot\text{ (9.4 }\cdot10^(-5)) \\ 35.72\cdot10^(-2) \\ 3.572\cdot10^(-3) \\ \end{gathered}

Then, we need to repeat the base (10) and add the exponents (3 + -5 = -2.

Let's adjust the to the scientific notation form, so let's move the dot to the left one place, so we'll end up with

3.572 x 10^-3
