Hoang 2Part 1:1)First, take Matrix A and use its values to substitute in the determinant equation for 3x3matrices.A =│A│=5 [(1*2)-(5*-1)]-2[(2*2)-(5*1)]+3[(2*-1)-(1*1)]Then, simplify to reach your answer.│A│= 242)First, take Matrix B and use its values to substitute in the determinant equation for 4x4matrices.B =│B│= (1)-(3)+0+0Then, expand by cofactors for the determinants of 3x3 still left.│B│= (1){(-2)[(1*0)-(-1*1)]-(5)[(0*0)-(-1*-3)]+(2)[(0*1)-(1*-3)]}-(3){(4)[(1*0)-(-1*1)]-(2)[(0*0)-(-1*-3)]+(1)[(0*1)-(1*-3)]}
