When the rank equals the number of variables we may be able to find a unique solution. In linear algebra the rank of a matrix a displaystyle a is the dimension of the vector space generated by its columns. Solved 2 Points Larlinalg8 4 6 011 0 100 Submissions U For any system with a as a coefficie…

Thus col a is 3 dimensional. A column space of a has associated with it a basis it s not a basis itself it might be if the null space contains only the zero vector but that s for a later video. Null Space Rank And Nullity Theorem In linear algebra the column space also called the range or image…
