विकल्प

• 5 × 4

• 5 × 5

• 4 × 5

• 5 × 3

Answer 1

A, B and C are three matrices each of order 5; the order of matrix CA + B² is 5 × 5.

Explanation:

Since A, B and C are square matrices of order 5 × 5

∴ CA is a matrix of 5 × 5 and B² is a matrix of order 5 × 5

∴ CA + B² is a matrix of order 5 × 5
