Question

(- 9 - 7i ) + (16 +5 i)

Answer 1

Answer:

 7 - 2i

Step-by-step explanation:

Here we have two complex numbers and wish to combine them.  Complex numbers have real and imaginary parts.  We sum up the real parts and the imaginary parts separately:

 -9 - 7i

+16 + 5i

------------

 7 - 2i      This is the sum of -9 -7i and 16 + 5i.
