Answer:
it depends on how many he can clean in a single hour.
if he cleans 2/5 pools thats 10 pools in 25 hours
Step-by-step explanation:
if he cleans one pool per hour, thats 25 pools in 25 hours. if he can clean 4 pools an hour, thats 100 pools in 25 hours.
3(3)(3)(3)(3), 3^5 or three to the fifth power
3 = 4 - 4^0 * 4/4
4 = 4^0 + 4^0 + 4^0 + 4^0
5 = 4^2 / (4^0 * 4) + 4^0
6 = 4^2 / 4 + 4^0 + 4^0
