Kua tāruatia ki te papatopenga
-b^{1}\frac{\mathrm{d}}{\mathrm{d}b}(b^{6})+b^{6}\frac{\mathrm{d}}{\mathrm{d}b}(-b^{1})
Mo ētahi pānga e rua e taea ana te pārōnaki, ko te pārōnaki o te hua o ngā pānga e rua ko te pānga tuatahi whakareatia ki te pārōnaki o te pānga tuarua tāpiri i te pānga tuarua whakareatia ki te pārōnaki o te mea tuatahi.
-b^{1}\times 6b^{6-1}+b^{6}\left(-1\right)b^{1-1}
Ko te pārōnaki o tētahi pūrau ko te tapeke o ngā pārōnaki o ōna kīanga tau. Ko te pārōnaki o tētahi kīanga tau pūmau ko 0. Ko te pārōnaki o te ax^{n} ko te nax^{n-1}.
-b^{1}\times 6b^{5}+b^{6}\left(-1\right)b^{0}
Whakarūnātia.
6\left(-1\right)b^{1+5}-b^{6}
Hei whakarea pū o te pūtake ōrite, tāpiri ana taupū.
-6b^{6}-b^{6}
Whakarūnātia.
-b^{7}
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 1 me te 6 kia riro ai te 7.
