Compute (3+4i) +(7 − 20i).
Sveta_85 [38]

Answer:

10 -16 i

Step-by-step explanation:

given,

(3+ 4 i) + (7 − 20 i)

for the given complex number

if the number is added of subtracted the real part will add or subtract to the real part and imaginary will add or subtract to the imaginary part.

now

                = (3+ 4 i) + (7 − 20 i)                                  

               = (3 + 7) + (4+(-20)) i                      

                = 10 + (-16) i                      

                = 10 -16 i                              

so, the given answer will be 10 -16 i
