Suppose CAequalsISubscript n (the ntimesn identity matrix). Show that the equation ABold xequalsBold 0 has only the trivial solution. Explain why A cannot have more columns than rows

See Explanation

Step-by-step explanation:

(a)For matrices A and C, given that: .

We want to show that Ax=0 has only the trivial solution

If Ax=0

Multiply both sides by C

This means that the system has only the trivial solution.

(b)If the system has more columns than rows, a free variable would occur when a column does not have a pivot. This would lead to a non-trivial solution.
