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.
