Question

If A = `[a_ÿ]` is a square matrix of order n, then elements (entries) a₁₁, a₂₂,------a_nn are said to constitute the ------ of the matrix A

पर्याय

• row

• column

• inverse

• diagonal

Answer 1

diagonal

Explanation:

If A= `[a_ÿ]` is a square matrix of order, n then elements (entries) a₁₁, a₂₂,------a_nn, are said to constitute the diagonal of the matrix A. Thus if

A = `[(1, -3, 1),(2, 4, -1),(3, 5, 6)]`

Then the elements of the diagonal of 'A' are 1, 4, 6.
