How do you write complex numbers in standard form?

The questions says: Write the complex number (1 - i)^3 in standard form.





How do I do that? And what is ';standard form';?How do you write complex numbers in standard form?
just expand the number





(1-i)^3=-2-2iHow do you write complex numbers in standard form?
The standard form for complex numbers is a+bi. To write your number in standard form, multiply (1-i)(1-i)(1-i) to get rid of the exponent, then simplify your i terms, keeping in mind that i^2 will equal -1 (so you will always end up with just i, never i^2 or i^3 or something). Then put the terms you have left, which will be a non-imaginary number plus a term including i, into the standard form a+bi. Essentially all they are asking is for you to rearrange the terms, so instead of 5i+2 you have 2+5i.
standard form means writing real and imaginary parts separately
