Q. Find the complex conjugate z1 of z1=−2i+7.z1=□
Identify parts of z1: Identify the real and imaginary parts of the complex number z1=−2i+7. In this case, 7 is the real part and −2 is the coefficient of the imaginary part i. Real part: 7 Imaginary part: −2
Determine complex conjugate: Determine the complex conjugate of z1=−2i+7. The complex conjugate of a complex number is obtained by changing the sign of the imaginary part. Therefore, the complex conjugate of −2i+7, denoted as zˉ1, is 7+2i. Complex conjugate: 7+2i
