Answer:
256r^6/t^9
Explanation:
start by dividing or simplifying the numbers on the fraction.
4096/16 = 256
Now you multiply the powers on top with the power outside the parenthesis. So (r^-2t^3)^-3
so you now have r^6 t^-9
your equation looks like 256 r^6 t^-9/r^0
But you can't have negative numbers for your powers so we are going to add/subtract with the bottom of the fraction. There are no t's to add/subtract so the t's move to the bottom and become positive. the r has a 0 power so it goes away.
Your equation is now. 256r^6/t^9
Hope that made sense. Good luck!
