Q.

z=91-27 i

\newline

What is the real part of

z

?

\newline

What is the imaginary part of

z

?

Complex number form: The complex number is given in the form $z = a + bi$ , where $a$ is the real part and $b$ is the imaginary part. In this case, $z = 91 - 27i$ .
Finding the real part: To find the real part of $z$ , we look at the term without the imaginary unit $i$ . The real part is $91$ .
Finding the imaginary part: To find the imaginary part of $z$ , we look at the coefficient of the term with the imaginary unit $i$ . The imaginary part is $-27$ , without the $i$ .
