Here are the essential concepts you must grasp in order to answer the question correctly.
Complex Numbers
Complex numbers are numbers that have a real part and an imaginary part, expressed in the form a + bi, where 'a' is the real part and 'b' is the coefficient of the imaginary unit 'i', which is defined as the square root of -1. Understanding complex numbers is essential for operations involving square roots of negative numbers, as they allow us to express these values in a meaningful way.

Standard Form of Complex Numbers
The standard form of a complex number is a + bi, where 'a' and 'b' are real numbers. When performing operations with complex numbers, it is important to express the final result in this form to clearly distinguish between the real and imaginary components. This format is crucial for further mathematical operations and applications in various fields.

Simplifying Square Roots of Negative Numbers
To simplify square roots of negative numbers, we use the property that √(-x) = i√x, where 'i' is the imaginary unit. This allows us to rewrite expressions involving square roots of negative values in terms of complex numbers. Mastery of this concept is necessary for correctly handling expressions like √-32 in the given problem.
