If x and y are positive integers, what is the value of x^y?

1) y^x= 9

2) x^(2y)= 64

Statement 2:

y^x = 9 have many different solutions: 9^1 =9; 3^2 = 9; -3^2 = 9...

Statement 2:

x^2y = 64 also has many solutions but they all give you the same result for x^y. Let's check:

2^6 = 64; so x=2 and y = 3 =>

x^y =84^3 = 64; so x=4 and y = 3/2 =>

x^y = 88^2 = 64; so x =8 and y =1 =>

x^y = 8Statement 2 is sufficient!
