Chapter 4: Q47. (page 174)

Perform the indicated matrix operations. If the matrix does not exist, write impossible47.3[4鈭�2鈭�17]

Short Answer

Expert verified

The answer is[12鈭�6鈭�321]

Step by step solution

01

- State the definition of a matrix.

A rectangular array of numbers arranged in rows and columns is called a matrix.

02

- Solve the matrix.

To evaluate the matrix use scalar multiplication.

Scalar multiplication is the method in which matrix is multiplied by a constant called scalar.

The matrix is:3[4鈭�2鈭�17]

Here, 3 is the scalar. Multiply each element of the matrix by 3.

3[4鈭�2鈭�17]=[12鈭�6鈭�321]

03

- State the conclusion.

Therefore, the resultant matrix is[12鈭�6鈭�321]
