The option given has no answer for the question.
the answer should be 1/x+y
choosing x/y is very wrong!!!!

Correct solution:
(X+Y)^-1 = 1/(X+Y)

I think the answer isn't among the options

Wrong. The answer is D.

In the laws of indices (xy) ^-¹

Is equal to (x+y)^-¹ or (x-¹ + y+-¹). Making the answer D.
