This one has me stumped. I know that there is no law of exponents explaining what happens for a sum of exponents with the same base, so I tried taking the natural log on both sides and adding the exponents that way as they multiply the same base, but it doesn't seem to be correct and I haven't been able to find a good explanation for how to proceed.
The problem is: 2^(x+2) + 2^(x+1) + 2^(x) = 3/4
If this question is against any of SE's rules I would be more than pleased to know of a good source to learn how to solve these types of problems, or even simply a nudge in the right direction! Thanks.
