^{1/4}((x+y)

^{1/2}−(y−1)x

^{−1}) = ?

The answers are given as multiple choice and I can't seem to get the right one. Here's my expanded equation:

(2*3+3)

^{1/4}((2+3)

^{1/2}- (2-1)(3

^{-1}) = ?

9

^{1/4}(5

^{1/2}- 2/2) = ?

9

^{1/4}(5

^{1/2}- 1) = ?

9

^{1/4}(5

^{1/2}) - 9

^{1/4 }= ?

And here's where I get stuck. I'm not sure how to simplify this more, but apparently the answer is 15

^{1/2}- 3

^{1/2}but I'm not sure how that is. Would be happy for some help!
