Whakaoti i te 6*frac{sqrt{2}}{2}-(-4/5)*frac{sqrt{2}}{2})

$$6 \cdot \frac { \sqrt { 2 } } { 2 } - ( - \frac { 4 } { 5 } ) \cdot \frac { \sqrt { 2 } } { 2 } )$$

Aromātai

$$\frac{17\sqrt{2}}{5}\approx 4.808326112$$

Whakakorea atu te tauwehe pūnoa nui rawa 2 i roto i te 6 me te 2.

$$3\sqrt{2}-\left(-\frac{4}{5}\times \frac{\sqrt{2}}{2}\right)$$

Me whakarea te -\frac{4}{5} ki te \frac{\sqrt{2}}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$3\sqrt{2}-\frac{-4\sqrt{2}}{5\times 2}$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$3\sqrt{2}-\frac{-2\sqrt{2}}{5}$$

Pahekotia te 3\sqrt{2} me -\frac{-2\sqrt{2}}{5}, ka \frac{17}{5}\sqrt{2}.

$$\frac{17}{5}\sqrt{2}$$
