Question

Which of the following expressions is the conjugate of a complex number with −6 as the real part and −5i as the imaginary part?

Answer 1

The complex number is -6-5i. The conjugate means just flip the sign of the imaginary part of the complex number. -6+5i is the answer.

Answer 2

Conjugate of complex number is -6 + 5i

Explanation:

a complex number with −6 as the real part and −5i as the imaginary part

For a complex number a+ib

a is the real part and b is the imaginary part

a complex number with −6 as the real part and −5i as the imaginary part can be written as -6-5i

the conjugate of a+ib is a-ib

The conjugate pf -6 -5i is -6+5i
