Question 749119: (x^-1+y^-1)^-1
I am unsure of how I am supposed to finish this problem. I flipped it becaues of the negative exponent and ended up with x^-1+y^-1/1 and then flipped it again because of the negative exponents on x and y. And ended up with 1/2x and 1/2y. I Don't recall in our lesson seeing problems with negative exponents on the inside and outside so I just figured you would keep flipping them til they were gone. I have a feeling that is incorrect.

At the lower level, focus on the main denominator. Lowest Common Denominator of the main denominator is xy. Try this: Multiply the whole complex fraction by . That should give you something which simplifies neatly into a noncomplex fraction.
