Solution 1
Power of a lens is defined as the ability of a lens to bend the rays of light. It is given by the reciprocal of focal length in metre.
Solution 2
The power of a lens is a measure of the deviation produced by it in the path of rays refracted through it.

(2) an erect image of the tree on the lens.
(3) no image as the screen has been removed
(4) an inverted image of the tree at the focus of the lens.
