True or False Werkzeug said: I don't know if this has already been stated but imaginary numbers (or complex numbers) are not real numbers, but all numbers are complex numbers because you can think of all numbers as having "+0i" … For example, the number [(3/4) + 4√2] is a complex number belonging to the field of all numbers of the form (p/q) + (r/s)√2. Explain why $\sqrt{-1}$ is not a real number. In situations where one is dealing only with real numbers, as in everyday life, there is of course no need to insist on each real number to be put in the form a+bi, eg. Why is every real number is a complex number? A complex number z has two parts - a real part and an imaginary part - and is of the form: z := x + iy. Sometimes all the real numbers are not talked about at once. Hence, false. Is every real number a complex number?give an example 1 See answer abus9994 is waiting for your help.
