  4. Contoh : Log 5,93 = 0,773 Mantise/mantisa Indeks/karakteristik

  5. TabelLogaritma Mencarinilailogaritma < 10 Berartimemilikiindeks/karakteristik = 0 Contoh : log 5,93 = … 773 Log 5,93 = 0,773

  6. Mencarinilailogaritma > 10 Berartimemilikiindeks/karakteristik = 1 Contoh : log 61,9 = … 792 Log 61,9 = 1,792

  7. Mencarinilailogaritma < 1 Berartimemilikiindeks/karakteristik = -1 Contoh : log 0,201 = … 303 Log 0,201 = 0,303 – 1 = - 0,697

  8. Tabel Anti Logaritma Tentukannilai x denganmenggunakantabel anti logaritmadari log x = 1,378 239 Log x = 1,378 diperoleh x = 23,9
