Let V be a vector space over C of dimenson n . We view V also as a vector space over R by restricting the scalar multiplication of C on V to R .Show that dimR(V) = 2n
Homework Equations
The Attempt at a Solution
I have to show that if x1,...xn form a basis of V over C then x1,...xn ix1,...ixn form a basis of V over R
but i still confuse about it
