3\left(\sqrt{2}\right)^{2}+12\sqrt{2}-4\sqrt{2}-16
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o 3\sqrt{2}-4 ki ia tau o \sqrt{2}+4.
3\times 2+12\sqrt{2}-4\sqrt{2}-16
Ko te pūrua o \sqrt{2} ko 2.
6+12\sqrt{2}-4\sqrt{2}-16
Whakareatia te 3 ki te 2, ka 6.
6+8\sqrt{2}-16
Pahekotia te 12\sqrt{2} me -4\sqrt{2}, ka 8\sqrt{2}.
-10+8\sqrt{2}
Tangohia te 16 i te 6, ka -10.
