The answer is C because X^-4 is also expressed as 1/X^4. A reciprocal of a number is 1 divided by that number. Therefore, it is seen that X^-4 is the reciprocal of X^4. Also, the reciprocal of X^-4 is 1/X^-4 which becomes 1/(1/X^4) simplifying to X^4. So X^4 is the reciprocal of X^-4, meaning both Sally and Tom are correct.
