It’s probably been 15 years since I last solved an equation like this. Don’t think I’ve done anything harder than arithmetic since then
27^4x=9^(x+1)
4x log 27=(x+1) log 9
4x log 3^3 = (x+1) log 3^2
4x*3 log 3 = (x+1) * 2 log 3
12x=2x+2
10x=2
x=0.2

I feel nothing. Used to get a little bit of satisfaction from solving things like this.

Is there an app that allows you to do a problem like this a day? I’d like to rediscover the fun of it.

Yes, I’d spend hours every week in high school doing less trivial versions of these kinds of problems for entrance exam prep…
Small dopamine hit each time, like a video game
There was an awesome app for social practice of GMAT/GRE/SAT questions called Grockit that Kaplan bought and killed. It was perfect!
