Tohaina
Kua tāruatia ki te papatopenga
5n^{7}\times 4
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 3 me te 4 kia riro ai te 7.
20n^{7}
Whakareatia te 5 ki te 4, ka 20.
\frac{\mathrm{d}}{\mathrm{d}n}(5n^{7}\times 4)
Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 3 me te 4 kia riro ai te 7.
\frac{\mathrm{d}}{\mathrm{d}n}(20n^{7})
Whakareatia te 5 ki te 4, ka 20.
7\times 20n^{7-1}

140n^{7-1}
Whakareatia 7 ki te 20.
140n^{6}
Tango 1 mai i 7.
