Note: In the web exercise below, you would input this answer as x^2y . Notice that exponents are input using the ‘ ^ ’ key.
Variables must be input in the order they appear in the first expression, going from left to right. For example, even though yx^2 is a correct answer, it is not recognized as correct.
