Whakaoti i te frac{6sqrt{12}+2sqrt{30}+15sqrt{18}+5sqrt{45}}{9sqrt{36}-sqrt{225}}

$$\frac { 6 \sqrt { 12 } + 2 \sqrt { 30 } + 15 \sqrt { 18 } + 5 \sqrt { 45 } } { 9 \sqrt { 36 } - \sqrt { 225 } }$$

Aromātai

$$\frac{2\sqrt{30}}{39}+\frac{4\sqrt{3}}{13}+\frac{5\sqrt{5}}{13}+\frac{15\sqrt{2}}{13}\approx 3.305633098$$

Ngā Upane Otinga

Tauwehea te 12=2^{2}\times 3. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 3} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{3}. Tuhia te pūtakerua o te 2^{2}.

$$\frac{6\times 2\sqrt{3}+2\sqrt{30}+15\sqrt{18}+5\sqrt{45}}{9\sqrt{36}-\sqrt{225}}$$

Whakareatia te 6 ki te 2, ka 12.

Tauwehea te 18=3^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{3^{2}\times 2} hei hua o ngā pūtake rua \sqrt{3^{2}}\sqrt{2}. Tuhia te pūtakerua o te 3^{2}.

$$\frac{12\sqrt{3}+2\sqrt{30}+15\times 3\sqrt{2}+5\sqrt{45}}{9\sqrt{36}-\sqrt{225}}$$

Whakareatia te 15 ki te 3, ka 45.

$$\frac{12\sqrt{3}+2\sqrt{30}+45\sqrt{2}+5\sqrt{45}}{9\sqrt{36}-\sqrt{225}}$$

Tauwehea te 45=3^{2}\times 5. Tuhia anō te pūtake rua o te hua \sqrt{3^{2}\times 5} hei hua o ngā pūtake rua \sqrt{3^{2}}\sqrt{5}. Tuhia te pūtakerua o te 3^{2}.

$$\frac{12\sqrt{3}+2\sqrt{30}+45\sqrt{2}+5\times 3\sqrt{5}}{9\sqrt{36}-\sqrt{225}}$$

Whakareatia te 5 ki te 3, ka 15.

$$\frac{12\sqrt{3}+2\sqrt{30}+45\sqrt{2}+15\sqrt{5}}{9\sqrt{36}-\sqrt{225}}$$

Tātaitia te pūtakerua o 36 kia tae ki 6.

$$\frac{12\sqrt{3}+2\sqrt{30}+45\sqrt{2}+15\sqrt{5}}{9\times 6-\sqrt{225}}$$

Whakareatia te 9 ki te 6, ka 54.

$$\frac{12\sqrt{3}+2\sqrt{30}+45\sqrt{2}+15\sqrt{5}}{54-\sqrt{225}}$$

Tātaitia te pūtakerua o 225 kia tae ki 15.

$$\frac{12\sqrt{3}+2\sqrt{30}+45\sqrt{2}+15\sqrt{5}}{54-15}$$
