In this complex number, assuming the equation is actually 18- √-25, the real part is already simplified. However, the imaginary part can be simplified by hiring "i" from the root with the relation i = √-1. This is done below:18 - √-2518 - √(-1)(25)18 - 5iFrom the options, the correct answer is 18 - 5i.
