Whakaoti i te 853-782/sqrt{frac{65{8}+63/8}}

$$\frac{ 853-782 }{ \sqrt{ \frac{ 65 }{ 8 } + \frac{ 63 }{ 8 } } }$$

Aromātai

$$\frac{71}{4}=17.75$$

Ngā Upane Otinga

Tangohia te 782 i te 853, ka 71.

$$\frac{71}{\sqrt{\frac{65}{8}+\frac{63}{8}}}$$

Tā te mea he rite te tauraro o \frac{65}{8} me \frac{63}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{71}{\sqrt{\frac{65+63}{8}}}$$

Tāpirihia te 65 ki te 63, ka 128.

$$\frac{71}{\sqrt{\frac{128}{8}}}$$

Whakawehea te 128 ki te 8, kia riro ko 16.

$$\frac{71}{\sqrt{16}}$$

Tātaitia te pūtakerua o 16 kia tae ki 4.

$$\frac{71}{4}$$

Tauwehe

$$\frac{71}{2 ^ {2}} = 17\frac{3}{4} = 17.75$$
