Write a formal proof for the following biconditional statement. For all integers n, n^3 is even if and only if n is even. [Hint: For one of the two directions of this proof, you might want to consider a proof using the contrapositive.] [Reminder: You may use the parity property, which states that each integer is either even or odd, but not both.]
