Jika ada soal seperti ini :

    4    625 f⁴g⁹h¹²  = (625)^1/4 (f⁴)^1/4 (g⁸)^1/4 (h¹²)^1/4

                                                   = (5⁴)^1/4 ( f ^4/4) (g^8/4) (h^12/4); ^{notes ; 5 pangkat 4 didapat dari pangkat 625 karena 625 = 5 pangkat 4}

                                  = 5 ^4/4  f¹ g²  h³

                                                   ^{= jawabannya adalah} : 5 f g² h³

Jika ada soal seperti ini :

          a^-10 b⁶  c^-3

                                   = a^-10-6 b^6-8 c^-3-(-12)

         a⁶     b⁸   c^-12       =a^-16 b^-2 c⁹

                                                     ^{jawabannya adalah} :               c9

                                                                     a ¹⁶ b²

² log 12 + ² log ½ -² log 3= ^{notes ; perhatikan pangkatnya pada soal ini pankatnya sama-sama 2, jika seperti ini maka operasi pnjumlahan dikalikan dahulu, baru nanti di bagi dgn operasi pengurangan,}

                                             = 2 log ( 12 x ½)

                                                                3

                                         = ² log 2 = 1
