If A({:(1,3,4),(3,-1,5),(-2,4,-3):})=({:...

If `A({:(1,3,4),(3,-1,5),(-2,4,-3):})=({:(3,-1,5),(1,3,4),(+4,-8,6):})`, then `A=`

A

`({:(1,0,0),(0,1,0),(0,0,-2):})`

B

`({:(0,1,0),(1,0,0),(0,0,1):})`

C

`({:(1,0,0),(1,0,0),(0,0,-2):})`

D

`({:(0,1,0),(1,0,0),(0,0,-2):})`

Text Solution

Verified by Experts

The correct Answer is:
D
`(d)` By observation its obvious that `R_(1)` and `R_(2)` are interchanged and `R_(3)` and `R.H.S-2` times `R_(3)` of `L.H.S`.
i.e., `R_(1)toR_(2)`, `R_(3)to2R_(3)impliesA=({:(0,1,0),(1,0,0),(0,0,-2):})`
