Loads of chat about remembering logs etc, I was expecting to see more number theory here as it’s a really lovely and applicable part of maths.
(As far as doing the calc, I thought it has to end in 7 becaus3 it’s the only one with a cub3 residue of 3 mod 10, which is what they say in post. Then 20 and 30 cubed are 8000 and 27000 respectively and assuming we’re restricting to Z 27 is the only possible answer)
