For each of the following statements, indicate if it is true (T) or false (F).
The set
is linearly independent.
For any given 2 x 2 matrices A, B and C such that A 02x2, if AB = AC
then we necessarily have B = C.
If the columns of a 4 x 4 matrix A are linearly independent, then the linear
system Ax = 0 has no solutions other than the trivial solution.
For any two 3 x 3 matrices A and B, we have (AT B")" = AB.
