Please do Exericse 2.15 please show a proof with your answer. Please show step by step and explain

Transcribed Image Text:In Chapter Two, with the definition of vector spaces, we seemed to have
opened up our studies to many examples of new structures besides the familiar
R¹'s. We now know that isn't the case. Any finite-dimensional vector space is
actually "the same" as a real space.
Exercises
✓2.10 Decide if the spaces are isomorphic.
(a) R², R4
(b) P5, R5 (c) M2x3, R6
(e) M2xk, M₁x2
(d) P5, M2x3
2.11 Which of these spaces are isomorphic to each other?
(a) R³ (b) M₂x2 (c) P3 (d) R4 (e) P₂
✓2.12 Consider the isomorphism RepB (-): P₁ → R² where B
image of each of these elements of the domain.
(a) 3-2x; (b) 2+2x; (c) x
(1,1+x). Find the
2.13 For which n is the space isomorphic to R"?
(a) P₁
(b) P₁
(c) M2x3
(d) the plane 2x -y +z = 0 subset of R³
(e) the vector space of linear combinations of three letters {ax+by+cz | a, b, c = R}
✓2.14 Show that if m n then R™ #R".
✓2.15 Is Mmxn Mnxm?
✓2.16 Are any two planes through the origin in R³ isomorphic?
