1.	If Z1 = 12+7i , Z2 = 9 – 3i , Z3 = 17 + 4i , then verify that (Z1 + Z2) + Z3 = Z1 + ( Z2 + Z3)
Answer» ong>Step-by-step explanation: LHS = (Z1 + Z2) + Z3 = (12+7i + 9 – 3i) + 17 + 4i = (21+4i) + 17+4i = 38 + 8i -----(1) RHS = Z1 + ( Z2 + Z3) = 12+7i + (9 – 3i + 17 + 4i) = 12+7i + (26+i) = 38 + 8i ------(2) from (1) & (2), LHS = RHS

If Z1 = 12+7i , Z2 = 9 – 3i , Z3 = 17 + 4i , then verify that (Z1 + Z2) + Z3 = Z1 + ( Z2 + Z3)

Answer»

ong>Step-by-step explanation:

LHS = (Z1 + Z2) + Z3

= (12+7i + 9 – 3i) + 17 + 4i

= (21+4i) + 17+4i

= 38 + 8i -----(1)

RHS = Z1 + ( Z2 + Z3)

= 12+7i + (9 – 3i + 17 + 4i)

= 12+7i + (26+i)

= 38 + 8i ------(2)

from (1) & (2),

LHS = RHS
