Question

Let R⁺ be the set of all non-negative real numbers equipped with the following operations:

(i) u ⊕ v = uv, for any u, v ∈ R⁺

(ii) α ⊙ u = u^α, for any α ∈ R and any u ∈ R⁺.

Show that R+ is a vector space (check the closure under the operations ⊕ and ⊙ and the 8 axioms).

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
