Identify complex number form: Identify the real and imaginary parts of the complex number.A complex number is in the form z=a+bi, where a is the real part and b is the imaginary part. In the given complex number z=8i−172, we can rewrite it as z=−172+8i to match the standard form.
Extract real part: Extract the real part from the complex number. The real part is the term without the imaginary unit i. In the rewritten form z=−172+8i, the real part is −172.
Extract imaginary part: Extract the imaginary part from the complex number. The imaginary part is the coefficient of the imaginary unit i. In the rewritten form z=−172+8i, the imaginary part is 8.
