(1+i)3 = 1 + 3i - 3 - i
= -2 + 2i
This is a complex number, and therefore cannot be plotted on a Cartesian plane.

9 cube !
The cube of A plus B is either A**3 + B or (A + B)**3 depending on what you intended to be cubed.
a complex number
Yes, the complex numbers, as well as the real numbers which are a subset of the complex numbers, form groups under addition.

A number of the form (a + bi) is a complex number.
It is called a complex number.
Yes, a+bi is standard form for a complex number. The numbers (a) and (b) are both real and i is √(-1)
The cube of A plus B is either A**3 + B or (A + B)**3 depending on what you intended to be cubed.
a complex number
(a+b)cube = a cube + b cube + 3a square b + 3ab square
(x - 4)(3x^3 + 4) The complex roots are the cube root of negative one third times two to the two thirds power and negative two to the two thirds power divided by the cube root of three
Yes, the complex numbers, as well as the real numbers which are a subset of the complex numbers, form groups under addition.
