jeden prosty przykład z logarytmow
wynik 3 i jedna trzecia
loga b = logc b / logc a ---- wzór
log 4 / log 2 + log 9 / log 3 - log 25 / log 125 = log2 4 + log3 9 - log 125 25 =
log2 2^2 + log3 3^2 - log125 (∛125)² =2 * log2 2 + 2 * log3 3 - log125 (125)^2/3 =
2 * 1 + 2 * 1 - 2/3 * 1 = 2 + 2 - 2/3 = 4 - 2/3 = 3 i 1/3
