Wow it took me 5 minutes to realize you swapped sides on the last step😭😭

This is a cool solution, but if you were in an exam, surely you would not have access to a lambert W function calculator? I am not from the US, so maybe in your entrance exams you allow computer access or something.

it’s like writing your answer in terms of sin, tan or cos. Your answer will be accepted if left in terms of the W function. For example leaving ur answer to a question as “1 + tan 28°” instead of “1.5317…” is the same as leaving ur answer to a question as “-W(25 * ln2)/ln2 +5” instead of “1.7156…”
