Text Solution

Verified by Experts

The correct Answer is:
N/a

`(i) L.H.S =[{:(5,-1),(6,7):}][{:(2,1),(3,4):}]`
`=[{:(10-3,5-4),(12+21,6+28):}]=[{:(7,1),(33,34):}]`
`R.H.S =[{:(2,1),(3,4):}][{:(5,-1),(6,7):}]`
`=[{:(10+6,-2+7),(15+24,-3+28):}]=[{:(16,5),(39,25):}]`
`therefore L.H.S .ne R.H.S. `hence proved .
`(ii) L.H.S =[{:(1,2,3),(0,1,0),(1,1,0):}][{:(-1,1,0),(0,-1,1),(2,3,4):}]`
`=[{:(-1+0+6,1-2+9,0+2+12),(0+0+0,0-1+0,0+1+0),(-1+0+0,1-1+0,0+1+0):}]`
`=[{:(5,8,14),(0,-1,1),(-1,0,1):}]`
`R.H.S=[{:(-1,1,0),(0,-1,1),( -1,0,1):}][{:(1,2,3),(0,1,0),(1,1,0):}]`
`=[{:(-1+0+0,-2+1+0,-3+0+0),(0+0+1,0-1+1,0+0+0),(2+0+4,4+3+4,6+0+0):}]`
`=[{:(-1,-1,-3),(1,0,0),(6,11,6):}]`
`therefore L.H.S ne R.H.S.` hence proved .
