Kua tāruatia ki te papatopenga
7^{2}-\left(4\sqrt{3}\right)^{2}
Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
49-\left(4\sqrt{3}\right)^{2}
Tātaihia te 7 mā te pū o 2, kia riro ko 49.
49-4^{2}\left(\sqrt{3}\right)^{2}
Whakarohaina te \left(4\sqrt{3}\right)^{2}.
49-16\left(\sqrt{3}\right)^{2}
Tātaihia te 4 mā te pū o 2, kia riro ko 16.
49-16\times 3
Ko te pūrua o \sqrt{3} ko 3.
49-48
Whakareatia te 16 ki te 3, ka 48.
1
Tangohia te 48 i te 49, ka 1.
