x + y = 5
Possible combinations :
x = 1 , y = 4
x = 2 , y = 3
x = 3 , y = 2
x = 4 , y = 1
x = 1 , y = 4
x ^ x + y ^ y = 31
1 ^ 2 + 2 ^ 2 = 31
1 + 4 = 31
Incorrect.
x = 2 , y = 3
x ^ x + y ^ y = 31
2 ^ 2 + 3 ^ 3 = 31
4 + 27 = 31
Correct.
x = 3 , y = 2
x ^ x + y ^ y = 31
3 ^ 3 + 2 ^ 2 = 31
27 + 4 = 31
Correct.
x = 4 , y = 1
x ^ x + y ^ y = 31
4 ^ 4 + 1 ^ 1 = 31
256 + 1 = 31
Incorrect.
The solutions are :
x = 2 , y = 3
and
x = 3 , y = 2
X^x+y^y=31
x+y=5
