Question

The expression 40(10)3t represents the number of people who have viewed an online video t weeks after the video is released. if the expression can be rewritten as 40(r)t, what is the value of r ?

Answer 1

We have the expression

`40(10)^(3t)`

To solve it we must remember the property:

`(a^m)^n=(a)^(m\cdot n)`

Here we have

`40(10)^(3\cdot t)`

Using the property it will be

`40(10^3)^t`

Now we solve it inside the parenthesis

`40(1000)^t`

Therefore r = 1000, the correct answer is the letter C.
