I need to prove those questions:
Why the next spaces are Hilbert space?
1. R^n?
2. Q^n?
3. C^n?

This should be quite obvious if you know what a Hilbert space is. It is a complete inner product space over either the real or complex field.Originally Posted by Shaharhada
We will not do your class assignments for you.
It isn't a classassignment.
I need a clue, how to slove it.
Please give me advice...
First, tell us what a Hilbert space is.
I need a explation what is Hilbert space.
I now the definition that it is inner product space, that every Kushi sequence is congruence sequence. The definitions "Kuhi sequence" and "congruence sequence" define by real sequences.
A Hilbert space is an inner product space which is complete in the norm defined by the inner product x^2 = (x,x).

What are you trying to do.
It is quite obvious that you don't understand the fundamentals.
If this is not a class assignment then it should be. You desperately need to take a mathematics class in basic real and functional analysis.
