Question

What is the value of n in the equation `2.3times10^9=(1times10^3)(2.3times10^n)`?

Answer 1

`n=6`

Explanation:

According to the law of exponents, when you multiply two exponents together, you must add them.
`9-3=6`, so 6 is equal to n.

To check your answer, simply multiply `2.3(1)10^6(10^3)`, which equals `2.3(10^9)`.

Sorry if this isn't the best explanation. I'm about to fall asleep. :|
