Final answer:
To calculate z2 - z1 for complex numbers, write both in standard form and subtract the real and imaginary parts, respectively. Typographical errors in the question prevent providing an exact answer.
Step-by-step explanation:
To find the difference between the complex numbers z1 and z2, we subtract them. The given complex numbers are z1 = 9 + (9/3)i and z2 = 2 + (/3)i. There seems to be a typo with z2, which should be written in standard form as 2 + (C/3)i, where C is a constant we need to determine.
Nevertheless, the subtraction proceeds as follows:
- Write both complex numbers in standard form (a + bi).
- Subtract the real parts and the imaginary parts separately.
- Express the difference as a new complex number.
Assuming the typographical issues in z2 are due to a missing constant, without specific values, we cannot find the exact difference. Once we have the correct form of z2, we would use the steps above to find z2 - z1.
