I think what you would do is subtract the "salvage value" of 4,000 from 22,000 to get 18,000. Then since you need the number of years, you would divide 22,000 by the depreciation price of 3,600 to get 5. It would take 5 years for the car's value to reach 4000, therefore she would want to sell it before then.
√65/√121=√65/11
√25/√36=5/6
I am not sure if that is your problem are the denominators square root too if so u just need to reduce and simplify. √65 is not a perfect square therefore you cannot reduce it cause it does not contain any perfect squares in its factors either.
Yes, that is because they go in the same direction, for instance, you rent it longer, the price increases accordingly.
