# Imaginary Numbers (*i*)

How to solve imaginary numbers problems: examples and their solutions.

## Examples

The radicand is (-),

which doesn't make sense in real numbers.

So these numbers are called imaginary numbers.

To simplify √-1,

change it to *i*.

(√-1 = *i*)

Then simplify the rest of the radical.
