Question

Which of these is a complex number?

Answer 1

Answer:

B.

Step-by-step explanation:

That would be B.

8/3 + √(-7/3) :-  because it consists of a real part ( the 8/3) and an imaginary part √(-7/3).

The √(-7/3) is usually written as √(7/3)i where i is √-1, so the complex number is 8/3 + √(7/3)i.

Answer 2

Answer:

b

Step-by-step explanation:

$\frac{8}{3}+\sqrt{-\frac{7}{3}} =\frac{8}{3}+i\sqrt{\frac{7}{3}}$
