The main thing i should've mentioned at the start is that the sqrt(-1) is represented by 'i'..... this is because the sqrt(-1) is a 'math error' on your calculator so using Imaginary Numbers allows us to deal with negative square roots.
For Example Sqrt(-16) is a math error but if we split it up we can say
sqrt(16) x sqrt(-1)
=(4) x (i)
= 4i
So essentially, Sqrt(-16) is 4i
