Putting a complex expression into standard form

The video tutorial explains how to express complex numbers in standard form, A + Bi. It begins by introducing the concept of standard form and the imaginary unit 'i'. The tutorial then explores the properties of 'i', including its powers, and demonstrates how to simplify expressions involving 'i'. Finally, it shows how to rewrite complex expressions in standard form by using these properties.

What is the standard form of a complex number?

• A * Bi

• A + Bi

• A - Bi

• A / Bi

What is the value of i^2?
