What is the conjugate of the complex number z = 2 + 5i?
Correct Answer: z̅ = 2 - 5i
- Step 1: Identify the complex number. In this case, the complex number is z = 2 + 5i.
- Step 2: Understand that the conjugate of a complex number is found by changing the sign of the imaginary part.
- Step 3: The imaginary part of z is 5i. To find the conjugate, we change 5i to -5i.
- Step 4: Write the conjugate using the real part and the new imaginary part. The real part is 2, and the new imaginary part is -5i.
- Step 5: Combine them to get the conjugate: z̅ = 2 - 5i.
