The answer is the first option. 7 left is not - 7 in this case. With these questions, you switch the signs. The vertical movement signs stay the same. Therefore, the answer is the first option.

Value of (-7+3i)-(2-6i)= -9 + 9i

Step-by-step explanation:

To find the value of the give expression: (-7+3i)-(2-6i)

Property of subtraction of complex number states that the subtract z_1-z_2 of two complex numbers z_1 = a+ib and z_2= c+id is defined as the complex number i.e

z_1 -z_2 = (a+ib)-(c+id) =(a-c) +i(b-d)

It is observed that while subtracting two complex numbers the real and imaginary parts of the system is obtained by subtracting the real and imaginary parts of the summands.

Now;

(-7+3i)-(2-6i) = (-7-2) +(3-(-6))i = -9 + (3+6)i = -9+9i

Therefore, the value of (-7+3i)-(2-6i) is, -9 + 9i.
