yep, you right. i didn't pay any attention to the maths, just the outcome. but then i tried to do the maths myself and got hella confused. turns out i was doing "10^1/3" (3.33) in google instead of "10^(1/3)" (1.154). so, that's lame - i guess gpt got confused about how to handle the exponential algebra. so it ends up being something like: $1,000,000 = $100,000(1+r)^3 10 = (1+r)^3 10^(1/3) = (1+r) 2.154 = 1+r 1.154 = r R = 115%
