Whakaoti i te frac{frac{sqrt{2}}{2}+3^2}{21}

$$\frac { \frac { \sqrt { 2 } } { 2 } + 3 ^ { 2 } } { 21 }$$

Aromātai

$$\frac{\sqrt{2}}{42}+\frac{3}{7}\approx 0.46224318$$

Ngā Hipanga Rongoā Poto

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\frac{\frac{\sqrt{2}}{2}+9}{21}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 9 ki te \frac{2}{2}.

$$\frac{\frac{\sqrt{2}}{2}+\frac{9\times 2}{2}}{21}$$

Tā te mea he rite te tauraro o \frac{\sqrt{2}}{2} me \frac{9\times 2}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{\sqrt{2}+9\times 2}{2}}{21}$$

Mahia ngā whakarea i roto o \sqrt{2}+9\times 2.

$$\frac{\frac{\sqrt{2}+18}{2}}{21}$$

Tuhia te \frac{\frac{\sqrt{2}+18}{2}}{21} hei hautanga kotahi.

$$\frac{\sqrt{2}+18}{2\times 21}$$

Whakareatia te 2 ki te 21, ka 42.

$$\frac{\sqrt{2}+18}{42}$$

Tauwehe

$$\frac{\sqrt{2} + 18}{42} = 0.4622431800565023$$
