Arithmetic
5 raruraru e ōrite ana ki:
\sqrt { 81 } - \sqrt { 025 } + \sqrt { \frac { 9 } { 4 } }
Tohaina
Kua tāruatia ki te papatopenga
9-\sqrt{0\times 25}+\sqrt{\frac{9}{4}}
Tātaitia te pūtakerua o 81 kia tae ki 9.
9-\sqrt{0}+\sqrt{\frac{9}{4}}
Whakareatia te 0 ki te 25, ka 0.
9-0+\sqrt{\frac{9}{4}}
Tātaitia te pūtakerua o 0 kia tae ki 0.
9+0+\sqrt{\frac{9}{4}}
Whakareatia te -1 ki te 0, ka 0.
9+\sqrt{\frac{9}{4}}
Tāpirihia te 9 ki te 0, ka 9.
9+\frac{3}{2}
Tuhia anō te pūtake rua o te whakawehenga \frac{9}{4} hei whakawehenga o ngā pūtake rua \frac{\sqrt{9}}{\sqrt{4}}. Tuhia te pūtakerua o te taurunga me te tauraro.
\frac{18}{2}+\frac{3}{2}
Me tahuri te 9 ki te hautau \frac{18}{2}.
\frac{18+3}{2}
Tā te mea he rite te tauraro o \frac{18}{2} me \frac{3}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{21}{2}
Tāpirihia te 18 ki te 3, ka 21.
