The term $$\mathbb{R}^n$$ refers to the n-dimensional Euclidean space, consisting of all possible ordered n-tuples of real numbers. It serves as a fundamental example of a vector space, where the vectors are represented as coordinates in this n-dimensional space. Understanding $$\mathbb{R}^n$$ helps in visualizing and working with concepts such as linear combinations, span, and dimensionality within the framework of vector spaces.
congrats on reading the definition of r^n. now let's actually learn it.
