Question

Problem b (4.0 x 10^2)(4.0 x 10^7)Problem c (7.0 x 10^-3)(6.0 x 10^6)Problem d (1.2 x 10^7)(2.2 x 10^-3)Problem e (2.0 x 10^-4)(7.1 x 10^9)

Answer 1

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}`
