Simplifying a complex expression and putting it in standard form

The video tutorial explains how to convert an expression into standard form, a + bi, where 'a' is the real part and 'b' is the imaginary part. It covers the concept of the imaginary unit 'i', its powers, and how they simplify. The tutorial demonstrates converting expressions involving powers of 'i' into standard form, emphasizing the importance of understanding 'i' squared and 'i' cubed. The final expression is presented in standard form with clear identification of the real and imaginary components.

What is the standard form of a complex number?
