Answer:
Step-by-step explanation:
Let's factor to see if it's a perfect cube: 3 is a factor, so let's divide: . 625 is no longer divisible by 3, but it is by 5, in particular it's . At this point we can start taking out of the cube root as much as we can:
A, B, F
8
56/7 = 8
0 10
1 20
0,0
1,20
2,40
3,50
4 60
p = 80 and q = 40
so p - q = 80 - 40 = 40
