First simplify, then evaluate: x ^ x + XY / x ^ x-xy ^ (y ^ y-xy / XY) divided by (x + y), where x = 1 / 3, y = - 3 | Math enthusiast | Mathematical art

First simplify, then evaluate: x ^ x + XY / x ^ x-xy ^ (y ^ y-xy / XY) divided by (x + y), where x = 1 / 3, y = - 3

The original formula = [(x × x + XY) × (Y × y-xy)] / [(x × x-xy) × XY × (x + y)]
=[x(x+y)×y(y-x)]×[x(x-y)×xy(x+y)]
=-1/x
Because x = 1 / 3, so - 1 / 3 = - 3
