Answer:
Option 3: 31-5i
Step-by-step explanation:
Simplify the imaginary and real parts separately.
The difference between m and r from the given expressions is 8
<h3>Indices and exponents</h3>
Given the following exponents
x^m/x^5=x^7
x^m = x^5 * x^7
x^m = x^12
Equate the powers
m = 12
For the expression
(x^r)³ = x^12
x^3r = x^12
3r = 12
r = 4
Take the difference
m - r = 12 - 4
m - r = 8
Hence the difference between m and r is 8
