- The statement is true for n = 1
- When the statement is true for n = k (where k is some positive integer), then the statement is also true for n = k + 1.
Also, if A is a square matrix of order n, then A2 is defined as AA. In general, Am = AA .... A (m times). where m is any positive integer.
Based on the above information, answer the following questions.
- If $\text{A}=\begin{bmatrix}3&-4\\1&-1\end{bmatrix},$ then for any positive integer n,
- $\text{A}^\text{n}=\begin{bmatrix}3\text{n}&-4\text{n}\\\text{n}&-\text{n}\end{bmatrix}$
- $\text{A}^\text{n}=\begin{bmatrix}1+2\text{n}&-4\text{n}\\\text{n}&1-2\text{n}\end{bmatrix}$
- $\text{A}^\text{n}=\begin{bmatrix}3\text{n}&-8\text{n}\\1&-\text{n}\end{bmatrix}$
- $\text{A}^\text{n}=\begin{bmatrix}1+3\text{n}&-4\text{n}\\\text{n}&1-3\text{n}\end{bmatrix}$
- If $\text{A}=\begin{bmatrix}1&2\\0&1\end{bmatrix},$ then |An|, where $\text{n}\in\text{ N},$ is equal to:
- 2n
- 3n
- n
- 1
- If $\text{A}=\begin{bmatrix}1&0\\1&1\end{bmatrix}$ and $\text{I}=\begin{bmatrix}1&0\\0&1\end{bmatrix}$ then which of the following holds for all natural numbers $\text{n}\geq1?$
- An = nA - (n - 1)I
- An = 2n-1 A - (n - 1)I
- An = nA + (n - 1)I
- An = 2n-1 A + (n - 1)I
- Let $\text{A}=\begin{bmatrix}\text{a}&0&0\\0&\text{a}&0\\0&0&\text{a}\end{bmatrix}$ and $\text{A}^\text{n}=[\text{a}_{\text{ij}}]_{3\times3}$ for some positive integer n, then the cofactor of a13 is:
- an
- -an
- 2an
- 0
- If A is a square matrix such that |A| = 2, then for any positive integer n, |An| is equal to:
- 0
- 2n
- 2n
- n2
