Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Imaginary Numbers
Imaginary numbers are defined as multiples of the imaginary unit 'i', where i is the square root of -1. They arise when taking the square root of negative numbers, which is not possible within the realm of real numbers. For example, √-3 can be expressed as i√3, allowing for operations involving negative square roots.

Square Roots of Negative Numbers
Properties of Square Roots
The properties of square roots include the product and quotient rules, which state that √a * √b = √(a*b) and √a / √b = √(a/b) for non-negative a and b. These properties can be extended to include imaginary numbers, enabling the simplification of expressions involving square roots of negative values.
