16. Which of the following statements is false?

(a) Let S = {v1, v2, . . . , vm} be a subset of a vector space V with dim(V) = n. If m > n, then S is linearly dependent.

(b) If A is an m × n matrix, then dim Nul A = n.

(c) If B is a basis for some finite-dimensional vector space W, then the change of coordinates matrix PB is always invertible.

(d) dim(R17) = 17.

(e) If B1 and B2 are both bases for the same vector space, then B1 and B2 have the same number of vectors.

True or False. 1. If the set {v1,v2} is a basis of R^2, then the set {v1,v1+v2} is also a basis of R^2. 2.If W be a vector space and V1,V2 are subspaces of W, then V1 u V2 is also a subspace of W. V1 u V2 denotes the union of V1 and V2, i.e. the set of vectors which belong to either V1 or V2 (or to both). 3.If W be a vector space and V1,V2 are subspaces...
