Given a stack of n disks arranged from largest on the bottom to smallest on top placed on a rod, together with two empty rods, what is the minimum number of moves required to move the stack from one rod to another, where moves are allowed only if they place smaller disks on top of larger disks?

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
