Answer:

40t^4

Step-by-step explanation:

I'm guessing you have to simplify the expression so...

first, on the top of the fraction there is a 5^2 which is just 25. 25*25 = 625, so the top of the fraction bar changes to 625 * t^8

The denominator is 10^3 = 1000. this changes it to 1000 * t^4

The hard part now is to simplify this. t^8 is just t*t*t*t*t*t*t*t. similarly t^4 is just t*t*t*t

Since there are 4 t's in both the numerator and denominator, this cancels it out and changes this to

\frac{625  \cdot t^4}{1000} which simplifies to \frac{5 \cdot t^4}{8}.

To get rid of the denominator, we multiply 8/8 to the fraction to get:

8(5 \cdot t^4), which if we distribute the 8 we get: 40t^4. Which is our answer!

Hope this helps!
