How to Find Complex Conjugate Then Apply Operations?

  • Begin with a complex number \( a + bi \), where \( a \) is the real part and \( b \) is the imaginary part.
  • Change the sign of the imaginary part to obtain \( a - bi \).
  • Perform addition, subtraction, multiplication, or division using the complex conjugate.

Solved Example

Q. Find the sum of 8+7i-8 + 7i and its complex conjugate.\newlineWrite your answer in the form a+bia+bi.
Solution:
  1. Identify complex conjugate: Identify the complex conjugate of 8+7i-8 + 7i.\newline Complex conjugate: 87i-8 - 7i
  2. Add original and conjugate: Add the original number and its complex conjugate.\newline 8+7i+(87i)-8 + 7i + (-8 - 7i)
  3. Combine like terms: Combine like terms.\newline Real part: 8+(8)=16-8 + (-8) = -16\newline Imaginary part: 7i7i=07i - 7i = 0
  4. Sum of real and imaginary parts: Sum of the real and imaginary parts.\newline 16+0i=16-16 + 0i = -16

To find the complex conjugate, change the sign of the imaginary part of the complex number. For example, the conjugate of \( 3 + 4i \) is \( 3 - 4i \). After finding the conjugate, we can apply operations like addition, subtraction, multiplication, or division to simplify expressions or solve equations. For detailed examples and steps, refer to the find complex conjugate then apply operations pdf.
