If matrix and A2 = kA, then write the value of k.

Given,∴ A2 = By matrix multiplication:A2 = As A2 = kA∴ ⇒ ∴ By equality of matrix and comparing both sides we see that k = 2.

If matrix and A² = kA, then write the value of k.

Given,

∴ A² =

By matrix multiplication:

A² =

As A² = kA

∴

⇒

∴ By equality of matrix and comparing both sides we see that k = 2.
