If A is a matrix of order 3xx4 and B is ...

If `A` is a matrix of order `3xx4` and `B` is a matrix of order `4xx3` , find the order of the matrix of `A Bdot`

Text Solution

Verified by Experts

Given that,
`A` is a matrix of order `3 times 4`
`B` is a matrix of order `4 times 3`

`=3 times underbrace(4*4) times 3=3 times 3`
`AB` will be order of `3 times 3`
