\frac{d}{d x} (- 5^{8 x^{2} - 1})

- 16 ln (5) \cdot 5^{8 x^{2} - 1} x

Solution steps

\frac{d}{d x} (- 5^{8 x^{2} - 1})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - \frac{d}{d x} (5^{8 x^{2} - 1})

Apply exponent rule:

a^{b} = e^{b l n (a)}

5^{8 x^{2} - 1} = e^{(8 x^{2} - 1) l n (5)}

= - \frac{d}{d x} (e^{(8 x^{2} - 1) l n (5)})

Apply the chain rule:

e^{(8 x^{2} - 1) l n (5)} \frac{d}{d x} ((8 x^{2} - 1) ln (5))

= e^{(8 x^{2} - 1) l n (5)} \frac{d}{d x} ((8 x^{2} - 1) ln (5))

\frac{d}{d x} ((8 x^{2} - 1) ln (5)) = 16 ln (5) x

= - e^{(8 x^{2} - 1) l n (5)} \cdot 16 ln (5) x

e^{(8 x^{2} - 1) l n (5)} = 5^{8 x^{2} - 1}

= - 16 ln (5) \cdot 5^{8 x^{2} - 1} x
