Th question say ahi that the complex number z=5 + 4i is in the set x.
Probably helps to post the full question and what youve tried.
A set is pretty much a list of numbers.
If you've done Aargand diagrams you should know what a complex number is so assume it is in this collection of other complex numbers. That's all you posted so... ?
