# Quizz vector spaces --- Introduction ---

This module contains 11 training exercises on basic notions of vector spaces.

Students may use them as a training tool for a better memorization of the lesson, while teachers may put them into a work sheet with activated time limit, so that proficiency can be tested.

### Two subsets

Let be a vector space. We have two subsets of , and , having respectively and elements. Answer:
