No.
It is not a requirement. However, it is easier to divide mentally if the denominator is a rational number.
Yes it is. All pure imaginary numbers (such as 5i) as well as all real numbers and any combination of real & imaginary (by adding, subtractin, multiplying, dividing) makes a complex number.
No difference. The set of complex numbers includes the set of imaginary numbers.
No. Dividing by zero is undefined. It does not result in anything.
imaginary numbers are numbers that are a negative square root, which is not possoble therefor it is called and imaginary number. ex the square root of -24 is an imaginary number
The "mean", or "mean average" in full, is obtained by adding up all the numbers and then dividing by the number of numbers there are. It is saying that if the numbers were all the same, this is what they would be.

An imaginary number is symbolized by the letter i
Midrange is the quantity obtained by adding the largest and smallest values in a set of numbers and dividing the result by 2.
imaginary numbers are numbers that are a negative square root, which is not possoble therefor it is called and imaginary number. ex the square root of -24 is an imaginary number
The average is obtained by adding the numbers and dividing by the number of numbers (in this case two)... so 4566+9=4575... then 4575/2 is... 2287.5 (the answer)
2 does belong to the set of imaginary numbers. Any real number is also imaginary. Imaginary numbers are the set of all numbers that can be expressed as a +b*i where "i" is the square root of negative one and "a" and "b" are both real numbers.
