Question

Select all the values that are equivalent to the given expression. Express your answer in scientific notation.(9.6times10^3)times(6.7times10^2)A. 6.432times10^5B. 6.432times10^6C. 64.32times10^5D. 64.32times10^6E. (9.6times6.7)times(10^3times10^2)

Answer 1

The given expression is

`(9.6*10^3)*(6.7*10^2)`

First, we group factors and powers.

`(9.6*6.7)(10^3*10^2)`

Then, we multiply.

`\begin{gathered} 64.32*10^(3+2) \\ 64.32*10^5 \end{gathered}`

Therefore, the right answer is C.
