If y varies directly as the square of x, that means that y=k*x^2. Plugging y=100 and x=5 into it, we get 100=k*5^2=k*25. Dividing by both sides, we get k=100/25=4. Going back to the original equation, we now know that y=4*x^2. Plugging 9=x in, we get 4*9^2=4*81=324=y

1: 6 ^ 3 If you mutiple it out then the negatives will cancel each other out
2: Right off the bat we can tell it is neither because a 3 times a 3 won't equal a 3.
3: 6 ^ 3 (flip fraction and change sign)
4: 6 ^ -3 (flip fraction and change sign)
