x=\frac{256}{\sqrt[4]{4}}
Calculate 4 to the power of 4 and get 256.
\sqrt[4]{4}=\sqrt[4]{2^{2}}=2^{\frac{2}{4}}=2^{\frac{1}{2}}=\sqrt{2}
Rewrite \sqrt[4]{4} as \sqrt[4]{2^{2}}. Convert from radical to exponential form and cancel out 2 in the exponent. Convert back to radical form.
x=\frac{256}{\sqrt{2}}
Insert the obtained value back in the expression.
x=\frac{256\sqrt{2}}{\left(\sqrt{2}\right)^{2}}
Rationalize the denominator of \frac{256}{\sqrt{2}} by multiplying numerator and denominator by \sqrt{2}.
x=\frac{256\sqrt{2}}{2}
The square of \sqrt{2} is 2.
x=128\sqrt{2}
Divide 256\sqrt{2} by 2 to get 128\sqrt{2}.
