razovaniyami (naprimer, vichislenie vremeni udvoeniya investitsiy pri 7% godovix s pomoshyu pravila 72) logarifmicheskie shkali (naprimer, shkala rixtera dlya zemletryaseniy, shkala detsibel dlya intensivnosti zvuka) sjimayut ogromnie chislovie diapazoni, uproshaya analiz yavleniy s silno razlichayusheysya intensivnostyu. 3. primenenie logarifmov reshenie pokazatelnix uravneniy, takix kak 2ˣ = 8, osushestvlyaetsya logarifmirovaniem (po osnovaniyu 10 ili naturalniy logarifm, ln): x ≈ 3. analogichno, uravneniya tipa eˣ = 10 reshayutsya s pomoshyu naturalnogo logarifma: x = ln(10) ≈ 2.303 logarifmi (logₐb = c oznachaet aᶜ = b) vajni dlya uprosheniya eksponentsialnix virajeniy i resheniya uravneniy. osnovnie osnovaniya: 10 (log₁₀) i e (naturalniy logarifm, ln). formula smeni osnovaniya pozvolyaet perexodit mejdu osnovaniyami: logₐb = logₓb / logₓa logarifmicheskie svoystva uproshayut vichisleniya. 4. reshenie pokazatelnix uravneniy s pomoshyu logarifmov logarifmi — obratnie eksponentsialnim funktsiyam: esli b = aˣ, to x = logₐ(b). eto vajno dlya resheniya eksponentsialnix uravneniy, primenyaemix v modelirovanii radioaktivnogo raspada (rascheti perioda poluraspada) …

i x, v kotoruyu nujno vozvesti osnovanie a, chtobi poluchit znachenie b. naprimer, log₁₀(100) = 2, tak kak 10² = 100 6. logarifmicheskie neravenstva logarifmi (po osnovaniyu 10 i e) — obratnie funktsii eksponentsialnix. reshenie logarifmicheskix uravneniy chasto trebuet formuli perexoda k novomu osnovaniyu (naprimer, iz osnovaniya 10 v osnovanie e (naturalniy logarifm, ln)) ili opredeleniya logarifma (naprimer, esli log₂(x) = 3, to x = 2³ = 8) logarifmicheskie uravneniya. 7. logarifmicheskie uravneniya logarifmi — obratnie funktsii eksponentam, predstavlyayut chislo kak pokazatel stepeni. formula smeni osnovaniya logarifmov pozvolyaet perevodit logarifmi mejdu raznimi osnovaniyami. formula smeni osnovaniya uproshaet vichisleniya, osobenno s neobichnimi osnovaniyami. 8. formula perevoda osnovaniy logarifmi prevrashayut umnojenie v slojenie, delenie v vichitanie, a vozvedenie v stepen v umnojenie. eto shiroko ispolzuetsya v vichisleniyax. logarifm (logb(x)) — eto pokazatel stepeni, v kotoruyu nujno vozvesti osnovanie 'b', chtobi poluchit chislo 'x' izobretenie logarifmov neperom revolyutsionizirovalo matematicheskie vichisleniya. 9. logarifm — …
