Question

Two matrices A = [a_ÿ] and B = [b_ÿ] are said to be equal if.

विकल्प

• They are of the same order

• a_ÿ = b_ÿ 

• Both they are of the same order and a_ÿ = b_ÿ 

• Neither they are of the same order nor a_ÿ = b_ÿ 

Answer 1

Both they are of the same order and a_ÿ = b_ÿ 

Explanation:

Two matrices are said to be equal if they have the same order and each element of 'A' equals the corresponding element of B, i.e. a_ÿ = b_ÿ for all i and j.

For example, `[(2, 3),(0, 1)]` and `[(2, 3),(0, 1)]` are equal matnces but `[(3, 2),(0, 1)]` and `[(2, 3),(0, 1)]` are not equal matrices.
