Question

If z1=2+3i and z2=2-4i then show the following on the argand diagram z1+Z2

Answer 1

Value of z1= 2+3i
Value of z2= 2-4i

So z1+z2
=(2+3i)+(2-4i)
= 2+3i + 2 - 4i
= 2 + 2 + 3i - 4i
= 4 - 1i

Thus, (z1+z2)= (4-1i)

Answer 2

Ardand diagram of $Z_{1}+Z_{2}$.

Step-by-step explanation:

1. Here

  $Z_{1}= 2+3\dot{i}$        ...1)

   $Z_{2}= 2-4\dot{i}$      ...2)

2. Then

   $Z=Z_{1}+Z_{2}$

   $Z=2+3\dot{i}+2-4\dot{i}$

 So

  $Z= 4-\dot{i}$

  Where

   Real Number = 4

   Imaginary number =-1

3. For argand diagram

   First make horizontal line for real number.

  Second draw vertical line for imaginary number.

4. First draw vertical line on positive 4 unit on real axis.

   second draw horizontal line on negative number 1 unit on omaginary axis. Joint intersection point to origin which represent argand of complex number Z.
