If x^2 = y^3 , where x and y are non negative and non zero integers, what is the greatest possible value of x and y from options below? Choose the correct choice:  A) x=27 , y=7  B) x=27, y=9  C) x=25, y=5  D) x=9, y=3  E) x=121, y=11
A. x=27 y=7 729 = 343 wrong   B. x=27, y=9 729 = 729 right   C. x=25, y=5 625 = 125 wrong   D. x=9, y =3 81 = 27 wrong   E. x=121, y =11 14641 = 1331 wrong   answer is x=27, y=9.
