Final answer:
The number 3+4i is a complex number, neither real nor rational nor irrational.
Step-by-step explanation:
The number 3 + 4i is an example of a complex number. Complex numbers consist of a real part and an imaginary part. The real part is represented by the number 3, and the imaginary part is represented by 4i.
A complex number is considered neither real nor rational nor irrational. It is a separate classification of numbers that includes both real and imaginary numbers.
In the given example, the real part is 3 which is a real number, and the imaginary part is 4i which represents the imaginary unit i multiplied by the real number 4.
