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

option: B is the correct answer.

                   B. complex numbers.

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.

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
