Given complex numbers m and n below, what is m + n?
m = 10 + i
n = 4 - 3i
A. 14-3i
B.14-2i
C.9+i
D.9+7i
I think it's B.
Yes, you are correct
10+4 = 14
i + -3i = -2i
(10+i) + (4-3i) = 14-2i
(a+b)(m+n)
To find the sum of complex numbers m and n, you simply add the real parts and imaginary parts separately.
m = 10 + i
n = 4 - 3i
Adding the real parts: 10 + 4 = 14
Adding the imaginary parts: 1 - 3 = -2
So, m + n = 14 - 2i.
Therefore, the correct answer is B. 14 - 2i.
To find the sum of two complex numbers, you simply add together the real parts and the imaginary parts separately.
Let's consider the given complex numbers:
m = 10 + i
n = 4 - 3i
Now, add the real parts (10 and 4): 10 + 4 = 14
Next, add the imaginary parts (1 and -3): i + (-3i) = -2i
Therefore, the sum of m and n is 14 - 2i.
So, your answer is B. (14 - 2i)
