Answer 3

To subtract the two complex numbers (-6,4+5,7) and (-1,8+4,7), you subtract their real parts and their imaginary parts separately. Here's how you do it:

(-6,4 + 5,7) - (-1,8 + 4,7)

First, subtract the real parts:

-6,4 - (-1,8) = -6,4 + 1,8 = -4,6

Next, subtract the imaginary parts:

(5,7) - (4,7) = 5,7 - 4,7 = 1,0

So, the result of the subtraction is:

-4,6 + 1,0i

Therefore, (-6,4+5,7) - (-1,8+4,7) = -4,6 + 1,0i.
