To write the complex conjugate of

Answer to Problem 47E
Complex conjugate:
Product of the number and its conjugate: 29
Explanation of Solution
Given:
The
Concept used:
To write a complex conjugate of a complex number, reverse the sign of imaginary part.
The unit of imaginary number,
The standard form a complex number is given as
Calculation:
First write the given complex number in standard form follows:
Reverse the sign of the imaginary part of the complex number to write its complex conjugate. So, the complex conjugate of
Now, multiply the number and its complex conjugate as follows:
Conclusion:
The complex conjugate of the given number is
