Q. z=20i+26What are the real and imaginary parts of z ?Choose 1 answer:(A) Re(z)=20 and Im(z)=26(B) Re(z)=26 and Im(z)=20i(C) Re(z)=20i and Im(z)=26(D) Re(z)=26 and Im(z)=20
Identifying the Complex Number: The complex number is given as z=20i+26. To find the real and imaginary parts, we need to identify the terms without the imaginary unit i as the real part, and the terms with the imaginary unit i as the imaginary part.
Finding the Real Part: The real part of the complex number z is the term without the imaginary unit i, which is 26. Therefore, Re(z)=26.
Finding the Imaginary Part: The imaginary part of the complex number z is the term with the imaginary unit i, which is 20i. To express the imaginary part, we only take the coefficient of i, which is 20. Therefore, Im(z)=20.
