1.	If f(y)=∣∣∣∣∣(1−y)a1b1(1−y)a1b2(1−y)a1b3(1−y)a2b1(1−y)a2b2(1−y)a2b3(1−y)a3b1(1−y)a3b2(1−y)a3b3∣∣∣∣∣ and ai,bi are even for i=1,2,3, then f′(2) is.
Answer» If $f (y) = ∣ ∣∣∣ ∣ \begin{matrix} (1 - y)^{a_{1} b_{1}} & (1 - y)^{a_{1} b_{2}} & (1 - y)^{a_{1} b_{3}} (1 - y)^{a_{2} b_{1}} & (1 - y)^{a_{2} b_{2}} & (1 - y)^{a_{2} b_{3}} (1 - y)^{a_{3} b_{1}} & (1 - y)^{a_{3} b_{2}} & (1 - y)^{a_{3} b_{3}} \end{matrix} ∣ ∣∣∣ ∣$ and $a_{i}, b_{i}$ are even for $i = 1, 2, 3,$ then $f^{'} (2)$ is.
