What is Linear Combination:

For a given vector vVF, it is referred to as linear combination of vectors v1,v2,...,vnV only when there exist scalars c1,c2,...,cn such that

v=i=1ncivi

This linear combination or linear span is very essential for determining the basis and dimension.

Given:

Given vectors are

v=1-23

v=-254+1-2-5+101

To Determine:

We represent the given vectors as a linear combination of e1,e2,e3.
