x^2^(1−(1/5))  = 25    x^2^(4/5)   = 25    2^(4/5) lnx = ln25    lnx = ((ln25)/( (2^4 )^(1/5) ))     x = e^((ln25)/( (2^4 )^(1/5) ))
$${x}^{\mathrm{2}^{\mathrm{1}−\frac{\mathrm{1}}{\mathrm{5}}} } =\:\mathrm{25} \\ $$$$ \\ $$$${x}^{\mathrm{2}^{\frac{\mathrm{4}}{\mathrm{5}}} } \:=\:\mathrm{25} \\ $$$$ \\ $$$$\mathrm{2}^{\frac{\mathrm{4}}{\mathrm{5}}} {lnx}\:=\:{ln}\mathrm{25} \\ $$$$ \\ $$$${lnx}\:=\:\frac{{ln}\mathrm{25}}{\:\sqrt[{\mathrm{5}}]{\mathrm{2}^{\mathrm{4}} }}\: \\ $$$$ \\ $$$${x}\:=\:{e}^{\frac{{ln}\mathrm{25}}{\:\sqrt[{\mathrm{5}}]{\mathrm{2}^{\mathrm{4}} }}} \\ $$
