x=\frac{256}{\sqrt[4]{4}}
Tātaihia te 4 mā te pū o 4, kia riro ko 256.
\sqrt[4]{4}=\sqrt[4]{2^{2}}=2^{\frac{2}{4}}=2^{\frac{1}{2}}=\sqrt{2}
Me tuhi anō te \sqrt[4]{4} ko \sqrt[4]{2^{2}}. Tahuritia i te āhua pūtake ki te āhua taupū ka whakakore i te 2 i te taupū. Tahuri anō ki te āhua pūtake.
x=\frac{256}{\sqrt{2}}
Me kōkuhu anō te uara i whiwhi i te kīanga.
x=\frac{256\sqrt{2}}{\left(\sqrt{2}\right)^{2}}
Whakangāwaritia te tauraro o \frac{256}{\sqrt{2}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{2}.
x=\frac{256\sqrt{2}}{2}
Ko te pūrua o \sqrt{2} ko 2.
x=128\sqrt{2}
Whakawehea te 256\sqrt{2} ki te 2, kia riro ko 128\sqrt{2}.
