simplify ln(xe^{-15x})

Solution

simplify

ln (x e^{- 15 x})

Solution

ln (x) - 15 x

Solution steps

ln (x e^{- 15 x})

Apply log rule:

lo g_{c} (ab) = lo g_{c} (a) + lo g_{c} (b)

ln (x e^{- 15 x}) = ln (x) + ln (e^{- 15 x})

= ln (x) + ln (e^{- 15 x})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (e^{- 15 x}) = - 15 x ln (e)

= ln (x) - 15 x ln (e)

15 x ln (e) = 15 x

= ln (x) - 15 x
