Math Problem Statement

Diketahui matriks A = [3 1; 2 -2]. Hasil dari A^3 adalah...

Solution

The question asks to find the matrix A3A^3 for the given matrix AA. Let's first extract the matrix AA and compute A3A^3.

Matrix AA is given as:

A=[3122]A = \begin{bmatrix} 3 & 1 \\ 2 & -2 \end{bmatrix}

To calculate A3A^3, we first find A2A^2, then multiply that result by AA again.

Let me calculate that for you.The matrix A3A^3 is:

A3=[3591810]A^3 = \begin{bmatrix} 35 & 9 \\ 18 & -10 \end{bmatrix}

This matches option D from the choices provided.

Do you need any further details or clarification?

Here are 5 related questions:

  1. How do we calculate the determinant of a 2x2 matrix?
  2. What is the inverse of matrix AA, if it exists?
  3. How can you use eigenvalues and eigenvectors to compute powers of matrices?
  4. What is the trace of a matrix, and what is its significance?
  5. How does matrix multiplication differ from scalar multiplication?

Tip: When multiplying matrices, always remember that matrix multiplication is not commutative (i.e., ABBAAB \neq BA in general).
