The correct Answer is:
To solve the problem, we will analyze the determinants \( D \) and \( D' \) and use properties of determinants to express \( D' \) in terms of \( D \). ### Step-by-Step Solution: 1. **Define the Determinants**: \[ D = \begin{vmatrix} a_1 & b_1 & c_1 \\ a_2 & b_2 & c_2 \\ a_3 & b_3 & c_3 \end{vmatrix} \] \[ D' = \begin{vmatrix} a_1 + p b_1 & b_1 + q c_1 & c_1 + r a_1 \\ a_2 + p b_2 & b_2 + q c_2 & c_2 + r a_2 \\ a_3 + p b_3 & b_3 + q c_3 & c_3 + r a_3 \end{vmatrix} \] 2. **Apply the Property of Determinants**: We can express \( D' \) as the sum of two determinants. Using the property that if one row of a determinant is expressed as a sum, we can separate it into two determinants: \[ D' = \begin{vmatrix} a_1 & b_1 & c_1 \\ a_2 & b_2 & c_2 \\ a_3 & b_3 & c_3 \end{vmatrix} + \begin{vmatrix} p b_1 & q c_1 & r a_1 \\ p b_2 & q c_2 & r a_2 \\ p b_3 & q c_3 & r a_3 \end{vmatrix} \] This gives us: \[ D' = D + \begin{vmatrix} p b_1 & q c_1 & r a_1 \\ p b_2 & q c_2 & r a_2 \\ p b_3 & q c_3 & r a_3 \end{vmatrix} \] 3. **Factor Out Constants**: We can factor out \( p \), \( q \), and \( r \) from the second determinant: \[ D' = D + p \cdot q \cdot r \begin{vmatrix} b_1 & c_1 & a_1 \\ b_2 & c_2 & a_2 \\ b_3 & c_3 & a_3 \end{vmatrix} \] Notice that the second determinant is actually \( D \) with columns rearranged, which does not change its value. Therefore: \[ D' = D + pqr \cdot D \] 4. **Combine the Terms**: We can combine the terms: \[ D' = D(1 + pqr) \] ### Final Result: Thus, we have established the relationship between \( D \) and \( D' \): \[ D' = D(1 + pqr) \]
