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, typically expressed in the form a + bi, where a is the real part and b is the coefficient of the imaginary unit i (where i² = -1). Understanding complex numbers is essential for performing operations such as addition, subtraction, multiplication, and division, especially when dealing with expressions that include imaginary components.

Division of Complex Numbers
Dividing complex numbers involves multiplying the numerator and the denominator by the conjugate of the denominator. The conjugate of a complex number a + bi is a - bi. This process eliminates the imaginary part in the denominator, allowing the expression to be simplified into standard form, which is a + bi, where both a and b are real numbers.

Standard Form of Complex Numbers
The standard form of a complex number is expressed as a + bi, where a and b are real numbers. In this form, a represents the real part, and b represents the imaginary part. Converting complex numbers into standard form is crucial for clarity and further mathematical operations, as it allows for easier interpretation and manipulation of the numbers in various mathematical contexts.
