The given inequality |z4||z2| represents the region given by none of these options, which is option D. Let's break down the reasoning behind this answer.
Explanation:
1. Definition of Absolute Value: The absolute value or modulus of a complex number z, denoted by |z|, is the distance from the origin to the point representing z in the complex plane.
2. Modulus of a Complex Number: The modulus of a complex number z = x + yi is given by |z| = √(x^2 + y^2), where x is the real part and y is the imaginary part of z.
3. Simplifying the Given Inequality: Let's simplify the given inequality step by step.
a. |z4| = |(z2)^2| = |z2|^2, using the property that |z^n| = |z|^n for any complex number z and integer n.
b. Therefore, the given inequality becomes |z2|^2|z2| > 0.
c. Since the square of a real number is always non-negative, we can conclude that |z2|^2 is always greater than or equal to 0.
d. Thus, the inequality becomes |z2| > 0.
4. Interpretation of |z2| > 0: The inequality |z2| > 0 represents all complex numbers except for the origin (0, 0) in the complex plane. In other words, it represents the entire complex plane excluding the origin.
5. Conclusion: Therefore, the region represented by the given inequality |z4||z2| is the entire complex plane excluding the origin, which is not represented by any of the given options (a), (b), or (c). Hence, the correct answer is option D (none of these).
In summary, the given inequality |z4||z2| represents the region given by none of the provided options (a), (b), or (c). The region is the entire complex plane excluding the origin.
