Question

Evaluate A3, if possible.
A= [7 3]
[-2 0]
Please help, having a hard time figuring these out

Answer 1

A3? A * 3?

Answer 2

\(\large A=
\begin{bmatrix}
7&3\\-2&0
\end{bmatrix}\qquad A3=A\cdot 3?\)

Answer 3

No its a to the 3rd power

Answer 4

hmm all I can think of is, then \(A=
\begin{bmatrix}
7&3\\-2&0
\end{bmatrix}\qquad A^3\implies \begin{bmatrix}
7&3\\-2&0
\end{bmatrix}\times \begin{bmatrix}
7&3\\-2&0
\end{bmatrix}\times \begin{bmatrix}
7&3\\-2&0
\end{bmatrix}\)
