once factorized
Answer:

Step-by-step explanation:
• 
Let's use FOIL (first, outer, inner, last) to solve this. We'll multiply the terms by one another in that fashion.

Rearrange in decreasing exponents.

I would round them so it would be 500 divided by 20
The answer should be close to 25

Step-by-step explanation:
if you do 6^3 you get 216
6*6*6=216
6*6=36
36*6=216
2*2*2*3*3*3=216
2*2=4
4*2=8
8*3=24
24*3=72
72*3=216
