how to solve the determinant 0 99 -998
-99 0 997
998 -997 0
Hence Taking the first row, we have
0 { 0*0 - 997*(-997)} - 99{ -99*0 - 997*998} -998 {-99*-997 - 0 *998}
= 0 + 99*997*998 - 99*997*998
= 0 (Ans)
Hence Taking the first row, we have
0 { 0*0 - 997*(-997)} - 99{ -99*0 - 997*998} -998 {-99*-997 - 0 *998}
= 0 + 99*997*998 - 99*997*998
= 0 (Ans)
