Answer with Step-by-step explanation:
We are given that
and are linearly independent.
By definition of linear independent there exits three scalar and such that
Where
We have to prove that and are linearly independent.
Let and such that
...(1)
..(2)
..(3)
Because and are linearly independent.
From equation (1) and (3)
...(4)
Adding equation (2) and (4)
From equation (1) and (2)
Hence, and area linearly independent.
