5 raruraru e ōrite ana ki:
\sqrt { 5 } + 12 \sqrt { 8 } - 3 \sqrt { 5 } + 4 \sqrt { 8 }
Tohaina
Kua tāruatia ki te papatopenga
\sqrt{5}+12\times 2\sqrt{2}-3\sqrt{5}+4\sqrt{8}
Tauwehea te 8=2^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 2} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{2}. Tuhia te pūtakerua o te 2^{2}.
\sqrt{5}+24\sqrt{2}-3\sqrt{5}+4\sqrt{8}
Whakareatia te 12 ki te 2, ka 24.
-2\sqrt{5}+24\sqrt{2}+4\sqrt{8}
Pahekotia te \sqrt{5} me -3\sqrt{5}, ka -2\sqrt{5}.
-2\sqrt{5}+24\sqrt{2}+4\times 2\sqrt{2}
Tauwehea te 8=2^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 2} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{2}. Tuhia te pūtakerua o te 2^{2}.
-2\sqrt{5}+24\sqrt{2}+8\sqrt{2}
Whakareatia te 4 ki te 2, ka 8.
-2\sqrt{5}+32\sqrt{2}
Pahekotia te 24\sqrt{2} me 8\sqrt{2}, ka 32\sqrt{2}.
