Q. Find the midpoint m m of z1=(7+8i) z_{1}=(7+8 i) and z2=(87i) z_{2}=(8-7 i) .\newlineExpress your answer in rectangular form.\newlinem= m=\square
  1. Concept of finding midpoint: Understand the concept of finding the midpoint of two complex numbers. The midpoint mm of two complex numbers z1z_1 and z2z_2 is given by the average of their real parts and the average of their imaginary parts. m = \frac{{\text{Re}(z_1) + \text{Re}(z_2)}}{\(2\)} + \frac{{\text{Im}(z_1) + \text{Im}(z_2)}}{\(2\)}i
  2. Identifying real and imaginary parts: Identify the real and imaginary parts of \(z_1 and z2z_2. For z1=7+8iz_1 = 7 + 8i, the real part Re(z1)\text{Re}(z_1) is 77 and the imaginary part Im(z1)\text{Im}(z_1) is 88. For z2=87iz_2 = 8 - 7i, the real part Re(z2)\text{Re}(z_2) is 88 and the imaginary part z2z_200 is z2z_211.
  3. Calculating average of real parts: Calculate the average of the real parts of z1z_1 and z2z_2.Re(z1)+Re(z2)2=7+82=152=7.5\frac{\text{Re}(z_1) + \text{Re}(z_2)}{2} = \frac{7 + 8}{2} = \frac{15}{2} = 7.5
  4. Calculating average of imaginary parts: Calculate the average of the imaginary parts of z1z_1 and z2z_2.Im(z1)+Im(z2)2=872=12=0.5\frac{\text{Im}(z_1) + \text{Im}(z_2)}{2} = \frac{8 - 7}{2} = \frac{1}{2} = 0.5
  5. Combining averages to find midpoint: Combine the averages to find the midpoint mm in rectangular form.m=7.5+0.5im = 7.5 + 0.5i
