Question

(-5,7-6,3)+(-5,7+4,5)

Answer 1

(-5.7-6.3)+(-5.7+4.5)= (-12)+(-1.2)=-12-1.2=-13.2

Answer 2

To add two complex numbers, you simply add their real parts and their imaginary parts separately. The complex number is represented in the form (real_part, imaginary_part).

Let's add the given complex numbers:

(-5, 7 - 6.3) + (-5.7, 4.5)

Add the real parts: -5 + (-5.7) = -10.7 Add the imaginary parts: (7 - 6.3) + 4.5 = 0.2 + 4.5 = 4.7

So, the sum is (-10.7, 4.7).
