|A*B| = |A* A {那堆数字}| = | |A| {那堆数字}| = |A|^3 | {那差袭堆歼庆汪数字氏仔}| = - |A|^3 = -27.
设A为三阶方阵,A*为A的伴随矩阵,且|A|=3.而A{100,001,010}(这堆数字是个矩阵）=B,则|A*B|=多少
|A*B| = |A* A {那堆数字}| = | |A| {那堆数字}| = |A|^3 | {那差袭堆歼庆汪数字氏仔}| = - |A|^3 = -27.
|A*B| = |A* A {那堆数字}| = | |A| {那堆数字}| = |A|^3 | {那差袭堆歼庆汪数字氏仔}| = - |A|^3 = -27.
