Science Question: how much force is needed to lift a car 17000N?

Ok, I've been racking my brains to try understand this problem without success. Does anyone know the answer? The question is: a hydraulic lift to lift a car weighing 17 000 Newtons. The ram used to increase the car had a cutting area 50 times that of the small piston lift. What is the size of the force applied on the smaller piston to lift the car?

17000/50 in the movement of 50 mm, the smallest piston enough fluid moves the piston to move a mm wider. It is a mechanical advantage of 50 (ignoring friction)
