I have a question for which I'm supposed to show that a function maps into "a hyperplane {u in ℝ^{5}:u^{5}=1}".

Does this mean that the target space is the set of vectors in ℝ^{5}such that the dot product of u with itself (5 times) is 1? Doesn't seem right...

Any clarification is appreciated.

EDIT: I think I figured it out. The u^5 is meant to denote the 5th coordinate, which makes a lot of sense in my case. Thank you for reading anyways.
