The

**power**, n,

**of a matrix**, A, is when you multiply the matrix by itself n times.

**A matrix can only be raised to a power if it has the same number of rows and columns**. Below you can visualize how to take the power of a matrix. (Note: The matrix is being multiplied by itself n times)

- Rewrite the problem (expand)
- Multiply the first two matrices
- Multiply the next matrix (if there is one) to the matrix produced in step 2
- Multiply the next matrix (if there is one) to the matrix produced in step 3

And so on until you get your final matrix.

Let’s see some examples of how to take the power of a matrix to better understand..
