Real solution:
Complex solutions:
Explanation:
32 = 2^532=25
We are given:
2^x = 1/32 = 1/(2^5) = 2^-52x=132=125=2−5
So the unique Real solution is
Complex solutions
e^(2pii) = 1e2πi=1
So:
2^x = 2^-5*e^(2kpii) = 2^(-5)*2^((2kpi)/ln(2) i) = 2^(-5+(2kpi)/ln(2)i2x=2−5⋅e2kπi=2−5⋅22kπln(2)i=2−5+2kπln(2)i
So
