\frac{d}{d x} ((x^{4} + 1)^{\frac{1}{2}})

\frac{2 x ^{3}}{( x ^{4} + 1 ) ^{\frac{1}{2}}}

Solution steps

\frac{d}{d x} ((x^{4} + 1)^{\frac{1}{2}})

Apply the chain rule:

\frac{1}{2 ( x ^{4} + 1 ) ^{\frac{1}{2}}} \frac{d}{d x} (x^{4} + 1)

= \frac{1}{2 ( x ^{4} + 1 ) ^{\frac{1}{2}}} \frac{d}{d x} (x^{4} + 1)

\frac{d}{d x} (x^{4} + 1) = 4 x^{3}

= \frac{1}{2 ( x ^{4} + 1 ) ^{\frac{1}{2}}} \cdot 4 x^{3}

Simplify

\frac{1}{2 ( x ^{4} + 1 ) ^{\frac{1}{2}}} \cdot 4 x^{3} : \frac{2 x ^{3}}{( x ^{4} + 1 ) ^{\frac{1}{2}}}

= \frac{2 x ^{3}}{( x ^{4} + 1 ) ^{\frac{1}{2}}}
