Final answer:
To identify a non-real complex number, one must look for the imaginary unit 'i' with a non-zero coefficient. The provided examples do not clearly indicate any number with such a unit. A hypothetical example of a non-real complex number is '5 + 2i'.
Step-by-step explanation:
The student's question regarding which of the following is a non-real complex number is a topic within the mathematics subject, particularly dealing with complex numbers. To identify a non-real complex number, we look for the presence of the imaginary unit 'i', which indicates the complex part of the number. Given the options provided in the examples, any number that includes this imaginary unit 'i' with a non-zero coefficient would be considered a non-real complex number. Unfortunately, none of the given statements clearly indicate a number in full with the necessary details to provide a concrete answer to whether it is a non-real complex number or not. However, if a hypothetical option, let's say 5 + 2i, were provided, this would be considered a non-real complex number because it includes an imaginary part.
