2 ½ is called a mixed number (a whole number and a fraction), not complex.

Complex number means there can be real and/or imaginary parts to a number. Without confusing you though, complex numbers include all of the real numbers (which include all fractions and mixed numbers).

No. It's a plain old mixed number .


How do you find square root of a complex number?

This is best done if the complex number is in polar coordinates - that is, a distance from the origin, and an angle. Take the square root of the argument (the absolute value) of the complex number; and half the angle.

Name 2 complex number that when multiplied together become a real number?

Any pair of complex conjugates do that.


What is a non real complex number?

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)


What is the complex number of its distance for the origin in the complex plane?

This is called the magnitude. It can be found (for a complex number a + bi) as:(where a & b are both real numbers and i is the imaginary unit)sqrt(a^2 + b^2)

What is the usefulness of the conjugate and its effect on other complex numbers?

The conjugate of a complex number is the same number (but the imaginary part has opposite sign). e.g.: A=[5i - 2] --> A*=[-5i - 2] Graphically, as you change the sign, you also change the direction of that vector. The conjugate it's used to solve operations with complex numbers. When a complex number is multiplied by its conjugate, the product is a real number. e.g.: 5/(2-i) --> then you multiply and divide by the complex conjugate (2+i) and get the following: 5(2+i)/(2-i)(2+i)=(10+5i)/5=2+i


What is the number divided by 2?

Half the number.


What are the fractions equivalent to 1 half?

All fractions having the form n / (2 * n) where n is a nonzero integer are equivalent to the fraction 1/2. This can actually be generalized to the form x / (2 * x) where x is a nonzero number (e.g. real number, complex number).


What is half of 235?

To calculate one-half of any number, divide the number by 2.
