Binomials cubed exercises can be solved using two methods. The first method consists in multiplying the binomial three times and fully expanding the expression. The second method is to use a standard formula that can simplify the resolution process. Here, we will look...

Binomials squared can be expanded using two main methods. We can write the binomial twice and perform the multiplication using the distributive property or we can use a standard formula and replace the values. Here, we will look at a summary of these two methods for...

We can perform any mathematical operation with imaginary and complex numbers. Similar to how we can add, subtract, multiply and divide these numbers, we can also raise them to powers. Here, we will learn what is the result of raising the imaginary unit to several...

The magnitude of a complex number is equal to its distance from the origin in the complex plane. The process of finding the magnitude of a complex number is very similar to the process of finding the distance between two points. Here, we will learn how to calculate...

To solve exercises with complex numbers, we have to start by analyzing the operation to be performed. If we have addition and subtraction, we simply have to add or subtract the real and imaginary parts separately. If we have multiplication, we use the distributive...
