sorry but this is not the right solution in my book....

here is the main problem :

then i tried to simplify it as i wrote in the 1st post

the solution set is {5} - January 15th 2012, 03:05 PMe^(i*pi)Re: i want help with finding solution set of exponential equation
Always state the problem in full, we can only answer what's put in front of us

Multiplying by each term in the second bracket:

Multiplying by each term in the second bracket

The expanded form is the sum of these:

Can you go from there? I expect a few terms will cancel - January 16th 2012, 12:38 AMmido22Re: i want help with finding solution set of exponential equation
