Exponential equation problem
Hi all. Am i doing this the right way? Thanks a lot in advance.
Latex cleaned up a little by Moderator.

Re: Exponential equation problem
Hi Soroban thanks a lot i completely forgot about that... The question in my book is "Find the solution set of the equation" Shouldn't a solution set have more than 1 vallue? Sorry i am totally new to LaTeX. That was my first attemp lol. Why didn't it show at all? I only see Math? where i entered the code.
Thanks again.

Re: Exponential equation problem
Hi Deon588,
You have one extra bracket in your first LaTeX statement, so it didn't show.
Continuing soroban's solution,

Re: Exponential equation problem
Hi. gAr thanks a lot for your effort. But that's a bit past my knowledge level. I'm busy doing a mathematics access course at my university which is more or less final year high school level math. My question is "Find the solution set of the equation" So from Soroban's solution i can see that there is only one value for x? Doesn't a solution set have to have more than one value?

Re: Exponential equation problem
Hi,
Ok. Do you know real numbers and complex numbers?
There's only one real solution, but multiple complex solutions.

Re: Exponential equation problem
No. I havn't done complex numbers at all. The only thing that has me wondering is the question "Find the solution set of..." As far as I know a solution set has more than 1 value? Do you think it would be ok to write "The solution set is {3}"

Re: Exponential equation problem
Ok, I guess you may write
