 Dec5 accepted Operations for operands with powers of different bases Dec5 comment Operations for operands with powers of different bases ok, thanks for your answer. The only reason why I wanted to do it is to have an approximate power of 2 (just compare with other stuff in my "computer science" class) Dec5 comment Operations for operands with powers of different bases Thanks, I know this is not precise at all, but is it valid to approximate $5^{19}$ to base 2 by doing $(2.23^2)^{19}$ Dec5 asked Operations for operands with powers of different bases Apr24 awarded Autobiographer Apr10 awarded Supporter Apr10 accepted Proving or disproving expression with implies operators Apr9 comment Proving or disproving expression with implies operators I think I'm allowed to; however, I don't see a straight forward way of doing for my particular scenario. I'll keep it in mind, thanks! Apr9 comment Proving or disproving expression with implies operators Thank you guys, I guess this means $$(A \implies B) \implies (C \implies B)$$ cannot be reduced to: $$A \implies C$$ Apr9 comment Proving or disproving expression with implies operators Does this mean that the "implies" operator is transitive? in other words if we have have: $$C \implies A and A \implies B$$ Can we infer the following? $$C \implies B$$ Apr8 asked Proving or disproving expression with implies operators May6 accepted Formula to assign weights to expert reviewers based on ratio between total votes and helpful votes May6 awarded Scholar May6 comment Formula to assign weights to expert reviewers based on ratio between total votes and helpful votes I appreciate everybody's help. The answer is indeed subjective and the solutions proposed are a great start. Another consideration is that records with few reviews (1/1) should probably be filtered out.
