To find the value of , we can use the property of determinants that states that multiplying a row (or column) of a matrix by a scalar multiplies the determinant of the matrix by the same scalar.In this case, we have the determinant of a 3x3 matrix and we want to find the value of such that the determinant of the matrix remains unchanged when the first row is multiplied by .The given determinant is: We want to find such that: Comparing the two determinants, we can see that the second determinant is obtained by multiplying the first row of the original determinant by . Therefore, we have: Since the determinants are equal, we have: Solving for , we get: Therefore, the value of is .
