Answer 1

To subtract complex numbers, subtract the real parts and the imaginary parts separately. The complex number in standard form is 8 - 3i.

Step-by-step explanation:

To subtract complex numbers, we subtract the real parts and the imaginary parts separately. In this case, we have (3i - 3) - (6i - 5). When we subtract the real parts, we get 3 - (-5) = 8 as the real part of the result. When we subtract the imaginary parts, we get 3i - 6i = -3i as the imaginary part of the result. Therefore, the complex number in standard form is 8 - 3i.
