Question

यदि A' = `[(-2,3),(1,2)] and "B" = [(-1,0),(1,2)]` है तो (A + 2B)' ज्ञात कीजिए।

Sum

Solution

दिया गया है, A' = `[(-2,3),(1,2)]` तथा `"B" = [(-1,0),(1,2)]`

इसलिए, A = `[(-2,1),(3,2)]`     [क्योंकि (A)' = A]

अब, (A + 2B) = `[(-2,1),(3,2)] + 2 [(-1,0),(1,2)]`

`= [(-2,1),(3,2)] + [(-2,0),(2,4)]`

`= [(-2 - 2, 1 + 0),(3 + 2, 2 + 4)]`

`= [(-4, 1),(5,6)]`

इसलिए, (A + 2B)' = `[(-4 , 5),(1,6)]`
