Let `A=[(2,4),(3,2)], B=[(1,3),(-2,5)], C=[(-2,5),(3,4)]`
Find each of the following:
`(i) A+B (ii) A-B (iii) 3A-C (iv) AB (v) BA`

Text Solution

Verified by Experts

The correct Answer is:
`(i) A+B=[(3,7),(1,7)] (ii) A-B=[(1,1),(5,-3)]`
`(iii) 3A-C=[(8,7),(6,2)] (iv) AB=[(-6,26),(-1,19)] (v) BA=[(11,10),(11,2)]`
