Question

Which of these is a complex number?

Answer 1

b

Explanation:

`(8)/(3)+\sqrt{-(7)/(3)} =(8)/(3)+i\sqrt{(7)/(3)}`

Answer 2

B.

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.
