17. Determine whether each statement is true or false, and provide a justifica-
tion or a counterexample.
a) Suppose that 71, 72, , Um are linear independent in a vector space V. Let
WE V such that w, k are linear independent for every k 1,2,...,m.
Then, 71, 72, , Um, are also linearly independent.

b) Suppose that 7₁, 72, 73 are linear independent in a vector space V. Then,
U1U2, U2₂ V3, 73 - 7₁ are also linearly independent.
c) Suppose that 7₁, 72, 73 are linear independent in a vector space V. Then,
V₁ + V2, V2 + V3, V3+ V₁ are also linearly independent.
