Whakaoti i te 7^3/120*21/3

$$\frac { 7 ^ { 3 } } { 120 } \cdot 2 \frac { 1 } { 3 }$$

Aromātai

$$\frac{2401}{360}\approx 6.669444444$$

Ngā Upane Otinga

Tātaihia te 7 mā te pū o 3, kia riro ko 343.

$$\frac{343}{120}\times \frac{2\times 3+1}{3}$$

Whakareatia te 2 ki te 3, ka 6.

$$\frac{343}{120}\times \frac{6+1}{3}$$

Tāpirihia te 6 ki te 1, ka 7.

$$\frac{343}{120}\times \frac{7}{3}$$

Me whakarea te \frac{343}{120} ki te \frac{7}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{343\times 7}{120\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{343\times 7}{120\times 3}.

$$\frac{2401}{360}$$

Tauwehe

$$\frac{7 ^ {4}}{2 ^ {3} \cdot 3 ^ {2} \cdot 5} = 6\frac{241}{360} = 6.669444444444444$$
