Best ResponseYou've already chosen the best response.2if matrix A is 4x2 and matrix B is 3x4, then A*B does not exist. It is not possible to multiply this way

Best ResponseYou've already chosen the best response.2let's say we had matrix A be of size 3x2 and matrix B of size 2x7

Best ResponseYou've already chosen the best response.2A*B is defined because the inner dimensions match dw:1437703383382:dw

Best ResponseYou've already chosen the best response.2A*B would be 3x7 because these are the outer dimensions dw:1437703430691:dw

Best ResponseYou've already chosen the best response.0The product of a 3 x 3 and a 6 x 6 matrix would be: Select one: a. 3 x 6 Incorrect b. 6 x 6 c. 3 x 3 d. Does not exist

Best ResponseYou've already chosen the best response.2you tell me (hint: look at the first problem we went over)

Best ResponseYou've already chosen the best response.0mmmm isnt it because the inner dimensions do NOT match. They need to be the same number to multiply the matrices

jim_thompson5910

Best ResponseYou've already chosen the best response.2correct, the 3 and 6 don't match so A*B doesn't exist
