Answer;


16*10^9

Step-by-step explanation:

Here, we want to get the product of the given expression

Since the base are the same,, we use the indices rule which is:


\text{ (a}^x)\text{ }*(a^y)=a^{x\text{ + y}}

We apply that in this same problem as follows:


\begin{gathered} \text{ 4.0}*\text{ 4.0}*10^2*10^7 \\ =4.0^2*10^(2+7) \\ =\text{ 16}*10^9 \end{gathered}
