Q. Find the complex conjugate

\overline{z_{1}}

of

z_{1}=-2 i+7

.

\newline

\overline{z_{1}}=\square

Identify parts of $z_{1}$ : Identify the real and imaginary parts of the complex number $z_{1} = -2i + 7$ . 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 $z_{1} = -2i + 7$ . 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 $\bar{z}_{1}$ , is $7 + 2i$ . Complex conjugate: $7 + 2i$
