Q. What is the conjugate of 85−81i ?−85+81i−81+85i−85−81i85+81i
Understand Conjugate Concept: Understand the concept of a conjugate. The conjugate of a complex number is obtained by changing the sign of the imaginary part. The real part remains unchanged. This means if we have a complex number a+bi, its conjugate is a−bi.
Identify Real and Imaginary Parts: Identify the real and imaginary parts of the given complex number.The given complex number is (85)−(81)i. Here, the real part is (85) and the imaginary part is −(81).
Apply Conjugate Concept: Apply the concept of conjugate to the given complex number.To find the conjugate, we change the sign of the imaginary part while keeping the real part the same. Therefore, the conjugate of (85)−(81)i is (85)+(81)i.
