Graphically, the conjugate of a complex number is its reflection on the real axis.
When a complex number is multiplied by its conjugate, the product is a real number and the imaginary number disappears.
The complex conjugate of a number in the form a + bi is simply the same number with the sign of the imaginary part changed. In this case, the number is 7 + 3i, so its complex conjugate would be 7 - 3i. This is because the complex conjugate reflects the number across the real axis on the complex plane.
For any number (a + bi), its conjugate is (a - bi), so the real part stays the same, and the imaginary part is negated.For this one, conjugate of [-3 - 9i] is: -3 + 9i
Yes. If you multiply X + iY by X - iY you get X2 + Y2. The imaginary parts cancel out.
Aamir jamal; All real numbers are complex numbers with 0 as its imaginary part.A real number is self-conjugate. e.g;a+0i self conjugate =a-0i i=iota
Since the imaginary portion of a real number is zero, the complex conjugate of a real number is the same number.

Their sum is real.

The graph of a complex number and its conjugate in the complex plane are reflections of each other across the real axis. If a complex number is represented as z = a + bi, its conjugate z* is a - bi. This symmetry across the real axis is a property of the complex conjugate relationship.
A number multiplied by its complex conjugate will result in a real number. Also, adding a number to its conjugate will result in a real number. But typically the multiplication is what is used.
A conjugate number refers to a complex number having both the imaginary and real parts of opposite signs and equal magnitude.
The conjugate will have equal magnitude. The angle from the real axis will be the same angle measure (but opposite direction).
For a complex number (a + bi), its conjugate is (a - bi). If the number is graphically plotted on the Complex Plane as [a,b], where the Real number is the horizontal component and Imaginary is vertical component, the Complex Conjugate is the point which is reflected across the real (horizontal) axis.
The conjugate of (84-3i) is (84+3i). This gives you a real number when multiplied.
