The real part of the complex number z = -3.6 - 1.3i is -3.6.
Step-by-step explanation:
The real part of the complex number z = -3.6 - 1.3i is simply the coefficient of the real term in the complex expression, which does not involve any 'i' terms. In this case, the real part is -3.6. When describing complex numbers in the form a + ib, where a and b are real constants, the real part is a. So, the real part re(z) of the complex number z is -3.6.
