Answer 2

Step-by-step explanation:

Before solving this Question we must know an important result,

a^(-m) = 1/(a^m)

There is a small correction in the problem,

(x^(-1) + y^(-1)) + (x^(-1) + y^(-1)) = x² + y² ——————— ——————— ————

x^(-1) y^(-1) xy

Otherwise, it is not possible to prove it, because LHS will become 2

Now, For the solution check the above attached image,

Hope it helped and you understood it........All the best
