Matrices - eigenvalues and eigenvectors questions. May be hard?

A matrix, $\mathbf{M}$, has 3 distinct eigenvalues, $\alpha, \beta$ and $\gamma$ with corresponding eigenvectors $\mathbf{u}, \mathbf{v}$ and $\mathbf{w}$.

It is given that the vector $\mathbf{p}= \mathbf{u} + 2\mathbf{v} -3\mathbf{w}$.

Find an expression for $\mathbf{M}^n \mathbf{p}$ in terms of $\mathbf{u}, \mathbf{v}$ and $\mathbf{w}$.

[Note. Your answer should not contain any matrices.]

Try this question and rate how hard it is. It might be really easy but I'm not sure.

Same.
Quickly give an answer if you can.

Well???
