Log feem ntau yog hais txog lub logarithm rau base 10 . Ln yeej yog hais txog lub logarithm rau lub hauv paus e. Qhov no kuj tseem hu ua ib qho logarithm ntau hom logarithm 10 (x) yog tus inverse lossis qhov ntxeev ntawm log₁₀(x), uas tuaj yeem txhais tau los ntawm log(x). Log(x) txhais tau hais tias lub hauv paus 10 logarithm thiab tuaj yeem sau ua log 10 (x). Nws qhia koj tias lub zog 10 yuav tsum tau tsa kom tau txais tus lej x. Tus inverse ntawm log10(x) yog 10x. https://www.vedantu.com › maths › value-of-log-10

Koj hloov log rau ln li cas?
Yog tias koj xav hloov ntawm cov logarithms thiab cov cav ntoo, siv ob qho hauv qab noequations:
- log10(x)=ln(x) / ln(10)
- ln(x)=log10(x) / log10(e)
Txoj cai lij choj siv rau ln?
Rau qhov yooj yim, peb yuav sau cov cai ntawm lub ntuj logarithm ln(x). Txoj cai siv rau txhua tus logarithm logbx, tsuas yog koj yuav tsum hloov qhov tshwm sim ntawm e nrog lub hauv paus tshiab b. Lub cav ntuj raug txhais los ntawm qhov sib npaug (1) thiab (2).
