Solution

We can start taking common factor in both sides and we got:


3^x(1+3+3^2)=2^x(1+2^2+2^3)^{}

and we can simplify like this:


3^x(13)=2^x(13)^{}

We can cancel the 13 in both sides and we got:


3^x=2^x^{}

Then we can do this using exponentials:


3^x-2^x=0^{}

We got:


x\ln (3)=x\ln (2)

then the only possible solution would be:

x=0
