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 conjugate is 7-5i

The conjugate is 7 - 3i is 7 + 3i.

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 concept of conjugate is usually used in complex numbers. If your complex number is a + bi, then its conjugate is a - bi.

Yes they do, complex conjugate only flips the sign of the imaginary part.

Since the imaginary portion of a real number is zero, the complex conjugate of a real number is the same number.

If you have a complex function in the form "a+ib", the (complex) conjugate is "a-ib". "Conjugate" is usually a function that the original function must be multiplied by to achieve a real number.

Yes. By definition, the complex conjugate of a+bi is a-bi and a+bi - (a - bi)= 2bi which is imaginary (or 0)

To find the complex conjugate of a number, change the sign in front of the imaginary part. Thus, the complex conjugate of 14 + 12i is simply 14 - 12i.
