Given :
To find : |A| ज्ञात कीजिए।
Solution :
हमें पता है की यदि
Det A = | A | = a₁₁ ( a₂₂ * a₃₃ - a₃₂ * a₂₃) - a₁₂ (a₂₁ * a₃₃ - a₃₁ * a₂₃) + a₁₃ (a₂₁ * a₃₂ - a₃₁ * a₂₂)
Det A = | A | = 1( 1* (-9) - (4)(-3)) - (1)(2 * (-9) - (5) *(-3) ) + (-2)((2)*(4) - (5) * 1)
= 1( -9 + 12) - (-18 + 15) - 2(8 - 5)
= 1(3) -(-3) -2(3)
= 3 + 3 - 6
= 0
Det A = | A | = 0
मान = 0
