⇒ 2(√(13))+(√3)−(√(2/3))  ⇒ 2(√(13))+(√3)−((√6)/3)  ⇒ ((6(√(13))+3(√3)−(√6))/3)  ⇒ ((6×3.6+3×1.7−1.41×1.7)/3)        ( (√6)=3.6  (√3)=1.7  (√2)=1.41)  ⇒ 6×1.2+1.7−.47×1.7  ⇒ 7.2 + 1.7 − .8  ⇒ 8.1
$$\Rightarrow\:\mathrm{2}\sqrt{\mathrm{13}}+\sqrt{\mathrm{3}}−\sqrt{\frac{\mathrm{2}}{\mathrm{3}}} \\ $$$$\Rightarrow\:\mathrm{2}\sqrt{\mathrm{13}}+\sqrt{\mathrm{3}}−\frac{\sqrt{\mathrm{6}}}{\mathrm{3}} \\ $$$$\Rightarrow\:\frac{\mathrm{6}\sqrt{\mathrm{13}}+\mathrm{3}\sqrt{\mathrm{3}}−\sqrt{\mathrm{6}}}{\mathrm{3}} \\ $$$$\Rightarrow\:\frac{\mathrm{6}×\mathrm{3}.\mathrm{6}+\mathrm{3}×\mathrm{1}.\mathrm{7}−\mathrm{1}.\mathrm{41}×\mathrm{1}.\mathrm{7}}{\mathrm{3}}\: \\ $$$$\:\:\:\:\:\left(\:\sqrt{\mathrm{6}}=\mathrm{3}.\mathrm{6}\:\:\sqrt{\mathrm{3}}=\mathrm{1}.\mathrm{7}\:\:\sqrt{\mathrm{2}}=\mathrm{1}.\mathrm{41}\right) \\ $$$$\Rightarrow\:\mathrm{6}×\mathrm{1}.\mathrm{2}+\mathrm{1}.\mathrm{7}−.\mathrm{47}×\mathrm{1}.\mathrm{7} \\ $$$$\Rightarrow\:\mathrm{7}.\mathrm{2}\:+\:\mathrm{1}.\mathrm{7}\:−\:.\mathrm{8} \\ $$$$\Rightarrow\:\mathrm{8}.\mathrm{1} \\ $$
