\frac{d}{d x} ((25 - x^{2})^{\frac{1}{2}})

- \frac{x}{( 25 - x ^{2} ) ^{\frac{1}{2}}}

Solution steps

\frac{d}{d x} ((25 - x^{2})^{\frac{1}{2}})

Apply the chain rule:

\frac{1}{2 ( 25 - x ^{2} ) ^{\frac{1}{2}}} \frac{d}{d x} (25 - x^{2})

= \frac{1}{2 ( 25 - x ^{2} ) ^{\frac{1}{2}}} \frac{d}{d x} (25 - x^{2})

\frac{d}{d x} (25 - x^{2}) = - 2 x

= \frac{1}{2 ( 25 - x ^{2} ) ^{\frac{1}{2}}} (- 2 x)

Simplify

\frac{1}{2 ( 25 - x ^{2} ) ^{\frac{1}{2}}} (- 2 x) : - \frac{x}{( 25 - x ^{2} ) ^{\frac{1}{2}}}

= - \frac{x}{( 25 - x ^{2} ) ^{\frac{1}{2}}}
