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

Yes, the complex numbers, as well as the real numbers which are a subset of the complex numbers, form groups under addition.

Multiply the numerator and denominator by the complex conjugate of the denominator ... [ root(2) minus i ]. This process is called 'rationalizing the denominator'.

A number of the form (a + bi) is a complex number.
It is called a complex number.
2 cube root 24 plus 3 cube root 81 is 18.7492444
Yes, a+bi is standard form for a complex number. The numbers (a) and (b) are both real and i is √(-1)
Yes, the complex numbers, as well as the real numbers which are a subset of the complex numbers, form groups under addition.

(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
It is 3/13 - 2/13*i
