1.

यदि `A=[(1,3,4),(2,0,1),(-3,2,3)],B=[(0,2,-1),(5,7,2),(-1,0,3)]` `C=[(2,-1,3),(6,8,5),(0,1,4)]` तब `4A-2B+3C` ज्ञात कीजिए।

Answer» `4A-3B+3C=4A+(-2)B+3C`
`=4[(1,3,4),(2,0,1),(-3,2,3)]+(-2)[(0,2,-1),(5,7,2),(-1,0,3)]`
`+3[(2,-1,3),(6,8,5),(0,1,4)]`
`=[(4,12,16),(8,0,4),(-12,8,12)]+[(0,-4,2),(-10,-14,-4),(2,0,-6)]`
`+[(6,-3,9),(18,24,15),(0,3,12)]`
`=[(4+0+6,12+(-4)+(-3),16+2+9),(8+(-10)+18,0+(-14)+24,4+(-4)+15),((-12)+2+0,8+0+3,12+(-6)+12)]`
`=[(10,5,27),(16,10,15),(-10,11,18)]`
