Imaginary Numbers (i)

Imaginary Numbers (i)

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

Examples

Simplify the given expressions. 1. square root(-3) 2. square root(-4) 3. square root(-20)

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.
