Answer 1

Hi friend, Harish here

Here is your answer:

We know  that,  Sum of two square numbers is zero only when each term is zero. Because square terms are never a negative integer.

Given that,

(2x - 4)² + (12 - 4y)² = 0.

Then, (2x - 4) =0 ,  & (12 - 4y) = 0.

 (2x - 4) =0 .                                      |                               (12 - 4y) = 0
                                                                  
⇒ 2x = 4                                                                           ⇒ 12 = 4y

⇒  x = 2                                                                            ⇒ y = 3.

Then,

⇒ $(x^{y} + y^{x}) = (2^{3} + 3^{2}) = 8 + 9 = 17$

Therefore the answer is  17.
