Question

Which of the following best describes the set of all numbers of the forn a+bi where a and b are any real numbers and i equals square root of -1? A. Rational Exponents B. complex numbers C. complex fractions D. Rational Exponents

Answer 1

Answer:

option: B is the correct answer.

                   B. complex numbers.

Step-by-step explanation:

We know that a complex number is always written in the form of :

                                 a+ib

  where a and b are real numbers and i is the square root of -1.

i is called an imaginary number.

If a>0 and b>0 then the point lie in the first quadrant.

if a>0 and b<0 then the point lie in the fourth quadrant.

if a<0 and b>0 then the point lie in the second quadrant.

if a<0 and b<0 then the point lie in the third quadrant.
