Question

What is the sum of the complex numbers 2 +3i and 4 +8i , where i equals square root of negative 1 end root ? ?
A) 17
B)  17i
C)  6 +11i
D) 8 +24i

hintHint:

Hint:
  • A complex number is a number that can be written in the form of a + i b , where a ,b  are real numbers.
  • For Adding two complex numbers, we add the real part together and the imaginary part together.

The correct answer is: The sum of the complex numbers 2+3i and 4+8i is 6+11i is .



    Explanation:
    • We have given two complex numbers,  2 plus 3 i text  and  end text 4 plus 8 i.
    • We have to find the summation of the two given complex numbers.
    • We will add real parts together and imaginary parts together.
    Step 1 of 1:                                                        
    We have given two complex numbers  2 plus 3 i text  and  end text 4 plus 8 i
    Now, for adding these two complex numbers, we will add the real part together and the imaginary part together.
    So,
    left parenthesis 2 plus 3 i right parenthesis plus left parenthesis 4 plus 8 i right parenthesis
    After rearranging, we get
    left parenthesis 2 plus 4 right parenthesis plus left parenthesis 3 i plus 8 i right parenthesis
    6 plus 11 i
    Final answer:
    The sum of the complex numbers 2 plus 3 i text  and  end text 4 plus 8 i text  is  end text 6 plus 11 i text .  end text
