log 102 = 0.30103 (approx.) The puag - 10 lub logarithm ntawm 2 yog tus lej x li ntawd 10 x = 2 . Koj tuaj yeem xam logarithms los ntawm tes siv qhov sib npaug xwb (thiab faib los ntawm lub zog ntawm 10 - uas yog tus lej hloov pauv) thiab qhov tseeb tias log 10 (x 10 )= 10 ⋅ log 10 x, txawm hais tias nws tsis yog qhov ua tau zoo heev
Ua li no, ua li cas koj thiaj nrhiav tau lub hauv paus 2?
Cov logarithm rau lub hauv paus 2 yog txhais rau txhua qhov kev sib cav sib ceg x ≠ 0. log2(x) rov sau logarithms rau qhov puag 2 nyob rau hauv cov nqe lus ntawm lub ntuj logarithm : log2(x) = ln(x)/ln( 2 ).
Tsis tas li ntawd, koj yuav ua li cas log puag 2 ntawm lub laij lej? Piv txwv li, los ntsuas lub logarithm base 2 ntawm 8, nkag ln(8)/ln( 2 ) nyob rau hauv koj tshuab xam zauv thiab nias ENTER . Koj yuav tsum tau 3 raws li koj cov lus teb. Sim nws rau koj tus kheej!
Xav txog qhov no, log 2 rau lub hauv paus 10 yog dab tsi?
log 102 = 0.30103 (kwv yees) Teb txuas. Lub Tsib Hlis 28, 2015. The puag - 10 logarithm ntawm 2 yog tus lej x li ntawd 10 x = 2 . Koj tuaj yeem xam logarithms los ntawm tes siv qhov sib npaug xwb (thiab faib los ntawm lub zog ntawm 10 - uas yog tus lej hloov pauv) thiab qhov tseeb tias log 10 (x 10 )= 10 ⋅ log 10 x, txawm hais tias nws tsis yog qhov ua tau zoo heev
