$$\frac{4^{4}\times4^{4}}{4^{4}+4^{4}}=x^{4}$$
$x=2\times 2^{\frac{3}{4}}i\approx 3.363585661i$
$x=2^{\frac{7}{4}}\approx 3.363585661$
$x=-2^{\frac{7}{4}}\approx -3.363585661$
$x=-2\times 2^{\frac{3}{4}}i\approx -0-3.363585661i$
$x=2^{\frac{7}{4}}\approx 3.363585661$
$x=-2^{\frac{7}{4}}\approx -3.363585661$
