BXAXC= { (1, a,x), (1, b,x), (2, a,x), (2, b,x)} That is, AXBXC is the set of all ordered triplets in which the elements occupy their respective places as in the name. That is, elements of the first set take first place in the triplet, elements of the second set take second place and elements of third set take third place in the triplet.

2015年8月21日 · Is the cardinality of AxBxC different to that of Ax (BxC), since AxBxC gives a 3 tuple, but Ax (BxC) gives a two tuple? but in such case, what would be the formula for calculating the cardinality of Ax (BxC) ? since in the sets A = {1,2} B = {3,4} C= {5,6} |AxBxC| = 2*2*2 = 8, but |Ax (BxC)| would be 2* (2*2) = 2* (4) = also 8...

给一个矩阵 左边 乘一个矩阵，相当于给该矩阵做相应的初等 行变换； 给一个矩阵 右边 乘一个矩阵，相当于给该矩阵做相应的初等 列变换。 所以 A\times B=A\times I\times B 相当于一个单位矩阵经过矩阵 A 对应的初等行变换和矩阵 B 对应的初等列变换； 而 B\times A=B\times I\times A 却相当于一个 单位矩阵 经过矩阵 B 对应的初等行变换和矩阵 A 对应的 初等列变换。 所以一般情况不相等。 从一个相当简单的角度来解释下，即从空间角度解释下矩阵乘法的意义是什么。 所 …

2) We have BxAxC = (BxA)xC when B, A, and C are all sets. This is because the Cartesian product of sets is associative. That is, for any sets A, B, and C, we have (A x B) x C = A x (B x C).

Our expert help has broken down your problem into an easy-to-learn solution you can count on. Here’s the best way to solve it. We have BxAxC = (BxA)xC when B, A, and C are all sets. …

2023年11月3日 · 今天看孩子作业，axbxc＝a×cxb＝bxcxa＝bxaxc这个叫结合律，axb＝bxa叫交换律。 真心不知道这种所谓的定律有什么区别，a(b+c)＝ab+ac叫分配率可以理解... 首页

(4 pts.) Let A= {a,b,c} and B={x,y} and C = {0,1}. What is |BxAxCl? Write BxAxC in set roster notation (i.e. list all elements). What is P(B X A X C)? Here P(X) indicates the power set of X
