\frac{d}{d x} (6^{- 2 x})

- ln (6) \cdot 9^{- x} \cdot 2^{- 2 x + 1}

Solution steps

\frac{d}{d x} (6^{- 2 x})

Simplify

6^{- 2 x} : 3 6^{- x}

= \frac{d}{d x} (3 6^{- x})

Apply exponent rule:

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

3 6^{- x} = e^{(- x) l n (36)}

= \frac{d}{d x} (e^{(- x) l n (36)})

Apply the chain rule:

e^{(- x) l n (36)} \frac{d}{d x} ((- x) ln (36))

= e^{(- x) l n (36)} \frac{d}{d x} ((- x) ln (36))

\frac{d}{d x} ((- x) ln (36)) = - 2 ln (6)

= e^{(- x) l n (36)} (- 2 ln (6))

Simplify

e^{(- x) l n (36)} (- 2 ln (6)) : - ln (6) \cdot 9^{- x} \cdot 2^{- 2 x + 1}

= - ln (6) \cdot 9^{- x} \cdot 2^{- 2 x + 1}

\int ((x^{2} + 2 x) cos (x)) d x

y^{^{'}} - y = 1 + 3 sin (t)

f (x) = 4 lo g_{6} (2)

f (x) = \frac{1}{2 x}, at x = 65

\frac{d}{d x} (cos (ln (x)))
