i^2=-1

Step-by-step explanation:

By definition, is known as "Imaginary unit" (It is also called "Unit imaginary number") and this is:

$i=\sqrt{-1}$

In this case you need to find i^2 , so you need to remember the following property:

$(\sqrt[n]{a})^n=a$

Therefore, in order to find i^2 , you must square both sides of the equation $i=\sqrt{-1}$ :

$(i)^2=(\sqrt{-1})^2$

FInally. you must apply the property shown before. Through this procedure you get that the value of i^2 is the shown below:

i^2=-1
