First we cube the quantity 2t. The quantity 2t cubed is 8t cubed. Now that our

fraction is simplified, we can change division to multiplication, and multiply

by the reciprocal of the second fraction. We just flip this fraction over. I'm

going to multiply these fractions straight across to get negative 24t to the

4th, divided by 40t to the 8th. You might have chosen to go ahead and simplify

the common factors here. Which is great. We know 8 divides into 24 three times

and 8 divides into 40, 5 times. When I look at my t's, I notice that I'll have

four more t's in the denominator, so I'll have negative three divided by five

times t to the fourth. That's some amazing algebra if you got that one correct.
