If A={:[(8),(-1),(-7)]:}andB={:[(2,5,-6)...

If `A={:[(8),(-1),(-7)]:}andB={:[(2,5,-6)]:}," then find "3A+B^(T)`.

A

`{:[(26),(2),(-27)]:}`

B

`{:[(36),(4),(-1)]:}`

C

`{:[(18),(2),(-9)]:}`

D

`{:[(2),(26),(-27)]:}`

Text Solution

Verified by Experts

The correct Answer is:
A
Given that `A={:[(8),(-1),(-7)]:}`
`B=[2" "5" "-6]`
`B^(T)={:[(2),(5),(-6)]:},3A={:[(24),(-3),(-21)]:}`
`3A+B^(T)={:[(24+2),(-3+5),(-6-22)]:}={:[(26),(2),(-27)]:}`
