- rerx 10y agon + (2 - 2) / 2 ?
- Grue3 10y agoNope. You can use three instances of number 2, all arithmetical operations and elementary special functions that are taught in high school.
- lifthrasiir 10y ago-log_2 log_2 sqrt(...(sqrt(2))...) {with n copies of sqrt} = -log_2 (2^-n log_2 2) = -log_2 (2^-n) = -(-n) = n. I would say that you need only one 2 if you replace log_2 by lg, so we should make lg taught in high schools... wink
