(来自 succeme) Abubuko.com,布布扣 是给定的方阵,特征值已知,其他小写字母为复数,用Abubuko.com,布布扣 的特征值表出下列行列式的值:

?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bbubuko.com,布布扣0bubuko.com,布布扣Ebubuko.com,布布扣abbubuko.com,布布扣n?1bubuko.com,布布扣Abubuko.com,布布扣n?1bubuko.com,布布扣bubuko.com,布布扣abbubuko.com,布布扣n?2bubuko.com,布布扣Abubuko.com,布布扣n?2bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣abbubuko.com,布布扣1bubuko.com,布布扣Abubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣1bubuko.com,布布扣Abubuko.com,布布扣bbubuko.com,布布扣0bubuko.com,布布扣Ebubuko.com,布布扣abbubuko.com,布布扣n?1bubuko.com,布布扣Abubuko.com,布布扣n?1bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣abbubuko.com,布布扣2bubuko.com,布布扣Abubuko.com,布布扣2bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣2bubuko.com,布布扣Abubuko.com,布布扣2bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣1bubuko.com,布布扣Abubuko.com,布布扣bbubuko.com,布布扣0bubuko.com,布布扣Ebubuko.com,布布扣?bubuko.com,布布扣abbubuko.com,布布扣3bubuko.com,布布扣Abubuko.com,布布扣3bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣n?1bubuko.com,布布扣Abubuko.com,布布扣n?1bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣n?2bubuko.com,布布扣Abubuko.com,布布扣n?2bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣n?3bubuko.com,布布扣Abubuko.com,布布扣n?3bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣bbubuko.com,布布扣0bubuko.com,布布扣Ebubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bubuko.com,布布扣

解答: (来自 torsor) 首先,若 a=0bubuko.com,布布扣 , 则所求矩阵是分块上三角阵,容易看出其行列式等于 bbubuko.com,布布扣nbubuko.com,布布扣2bubuko.com,布布扣bubuko.com,布布扣0bubuko.com,布布扣bubuko.com,布布扣 . 以下设 a0bubuko.com,布布扣 , 并且 ωbubuko.com,布布扣1bubuko.com,布布扣,?,ωbubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣 xbubuko.com,布布扣nbubuko.com,布布扣?abubuko.com,布布扣 nbubuko.com,布布扣 个不同的根. 设复系数多项式

f(x)=bbubuko.com,布布扣0bubuko.com,布布扣+bbubuko.com,布布扣1bubuko.com,布布扣x+?+bbubuko.com,布布扣n?1bubuko.com,布布扣xbubuko.com,布布扣n?1bubuko.com,布布扣.bubuko.com,布布扣
考虑如下分块矩阵的乘法:
?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bbubuko.com,布布扣0bubuko.com,布布扣bubuko.com,布布扣abbubuko.com,布布扣n?1bubuko.com,布布扣Abubuko.com,布布扣n?1bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣abbubuko.com,布布扣1bubuko.com,布布扣Abubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣1bubuko.com,布布扣Abubuko.com,布布扣bbubuko.com,布布扣0bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣abbubuko.com,布布扣2bubuko.com,布布扣Abubuko.com,布布扣2bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣2bubuko.com,布布扣Abubuko.com,布布扣2bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣1bubuko.com,布布扣Abubuko.com,布布扣?bubuko.com,布布扣abbubuko.com,布布扣3bubuko.com,布布扣Abubuko.com,布布扣3bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣n?1bubuko.com,布布扣Abubuko.com,布布扣n?1bubuko.com,布布扣bubuko.com,布布扣bbubuko.com,布布扣n?2bubuko.com,布布扣Abubuko.com,布布扣n?2bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣bbubuko.com,布布扣0bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣ωbubuko.com,布布扣1bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣ωbubuko.com,布布扣n?1bubuko.com,布布扣1bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣ωbubuko.com,布布扣2bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣ωbubuko.com,布布扣n?1bubuko.com,布布扣2bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣ωbubuko.com,布布扣3bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣ωbubuko.com,布布扣n?1bubuko.com,布布扣3bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣ωbubuko.com,布布扣nbubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣ωbubuko.com,布布扣n?1bubuko.com,布布扣nbubuko.com,布布扣Ibubuko.com,布布扣nbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣?bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣
