(C) આપેલ છે,$\Delta = \left| \begin{array}{ccc} 41 & 42 & 43 \ 44 & 45 & 46 \ 47 & 48 & 49 \end{array} ight|$.સ્તંભ પ્રક્રિયાઓ $C_2 	o C_2 - C_1$ અને $C_3 	o C_3 - C_2$ લાગુ પાડતા:$C_2 - C_1 = \begin{bmatrix} 42-41 \ 45-44 \ 48-47 \end{bmatrix} = \begin{bmatrix} 1 \ 1 \ 1 \end{bmatrix}$$C_3 - C_2 = \begin{bmatrix} 43-42 \ 46-45 \ 49-48 \end{bmatrix} = \begin{bmatrix} 1 \ 1 \ 1 \end{bmatrix}$તેથી,$\Delta = \left| \begin{array}{ccc} 41 & 1 & 1 \ 44 & 1 & 1 \ 47 & 1 & 1 \end{array} ight|$.અહીં બે સ્તંભો ($C_2$ અને $C_3$) સમાન હોવાથી,નિશ્ચાયકનું મૂલ્ય $0$ થાય છે.
