For this assignment you submit answer by question parts. The number of submissions for each question part only changes if you submit or change the answer. Your best submission for each question parts is used for your score. Write the complex conjugate of the complex number. -3 - squareroot 3i -3 + i squareroot 3 Multiply the number by its complex conjugate. (Simplify your answer completely.)

Solution

conjugate of -3 -i3 is -3 +i3

now

(-3 -i3)*(-3 +i3)

=((-3)*(-3))+((-3)*(i3)) +((-i3) *(-3)) +((-i3) *(i3))

=9-(i33)) +(i33) -(3i²)

=9 -(3i²)

=9 -(3*(-1))

=9 -(-3)

=9 +3

=12
