Question

For i =  $\sqrt{-1}$ , the sum of  $($ $-3$   $+$  4 $i$ $)$   $+$ $($ $-4-3i)$  is equal to

cdquestions Admin · Accepted Answer

To find the sum of the complex numbers  $($ $-3$   $+$ $4$ $i$ $)$  and $($ $-4-3i)$ we can add the real parts and the imaginary parts separately Real parts: ⇒ $-3+(-4)=-7$ Imaginary parts: ⇒ $4i+(-3i)=1i$  or simply  $i$ The sum is: $-7+i$ So the correct option is (C): $-7+i$
