Q43. In a determinant if m is the number of elements
of a row and n is the number of elements of a
column, then
(A) m=n
(B) m<n
(C) m>n
(D) mun​

Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

In a determinant if m is the number of elements of a row and n is the number of elements of column, then

(A) m=n

(B) m<n

(C) m>n

(D) mun

CONCEPT TO BE IMPLEMENTED

A determinant of order n is a block of $\sf{ {n}^{2} }$ elements arranged in the form of a square along n rows and n columns

EVALUATION

Here it is given that In a determinant if m is the number of elements of a row and n is the number of elements of a column

Since in a determinant

Number of rows = Number of columns

∴ m = n

FINAL ANSWER

Hence the correct option is

(A) m = n
