Are you just suppose to know from memorization that -log(0.01)=2?...i'm a little confused here...are you guys memorizing the log graph or building each? bc to be honest i have no freaking idea how to build the above solution! 😕

log(.01) = log (1/100) = log(10^-2) = -2
so -log(.01) = -(-2) = 2

rocket surgery----man i feel stupid....thanks again...thats twice in one day 🙂

no problem, logs can get tricky!

Little tip I learned from BR: you can actually compute any log if you know log(2) and log (3). I've gotten accustomed to using my calculator over the past two years and completely forgot how to do a lot of this math.

Oh and log(10^x) = x

That formula should help.
