Come si risolve log3 di 2? (base 3)?

DON’T LAUGH, mica is a problem or an equation!

If you value the expression

* L = log(3, 2) [~= 15601/24727 ~= 0.63092975]

and I don’t have a logaritmi table in base tre, but only one logaritmi in base B, allora puoi applicare la ben not proprietà

* log(b, x) = log(B, x)/log(B, b)

delle funzioni logarithm and valutare il rapporto

* L = log(3, 2) = log(B, 2)/log(B, 3)

ESEMPI por le tavole più diffuse (logarithm to sei cifre)

* L = log(3, 2) = log(10, 2)/log(10, 3) ~= 0.301030/0.477121 ~= 0.6309300994925816

* L = log(3, 2) = log(e, 2)/log(e, 3) ~= 0.693147/1.09861 ~= 0.6309309035963626

————————————

CHECK (a cipher undici)

* 3^(0.301030/0.477121) ~= 2.0000007601

* 3^(0.693147/1.09861) ~= 2.0000025269

* 3^(15601/24727) ~= 1.9999999985
