To take the square root of a complex number:* Write the original complex number in polar notation (absolute value and angle).
* For the square root, the angle will be half the angle. The absolute value will be the square root of that of the original number.
* There is a second square root: the same as above, but add 180 degrees (or pi, if using radians) to the angle.
* If you wish, you can convert the result(s) back to rectangular coordinates, i.e., real number + imaginary number.
Most scientific calculators have functions to convert from rectangular to polar and vice versa.
"a + bi" is a common way to write a complex number. Here, "a" and "b" are real numbers.Another common way to write a complex number is in polar coordinates - basically specifying the distance from zero, and an angle.

The conjugate is 7-5i

A number of the form (a + bi) is a complex number.
It is just 11+8i.

A complex number comes in two parts: a real part and an imaginary part. If the value of the real part is a and the value of the imaginary part is b, the number is written as a + bi.
Complex numbers are written in the form (a+bi), where i is the square root of -1.A real number does not have any reference to i in it.A non real complex number is going to be a complex number with a non-zero value for b, so any number that requires you to write the number i is going to be an answer to your question.2+2i for example. (2 plus 2 times i)

It is called a complex number.

No. There is no number you can write that someone else can't come along and write "plus one" after it.
