simplify ln((e^{-2x})/2)

Solution

simplify

ln (\frac{e ^{- 2 x}}{2})

Solution

- 2 x - ln (2)

Solution steps

ln (\frac{e ^{- 2 x}}{2})

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

ln (\frac{e ^{- 2 x}}{2}) = ln (e^{- 2 x}) - ln (2)

= ln (e^{- 2 x}) - ln (2)

Apply log rule:

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

ln (e^{- 2 x}) = - 2 x ln (e)

= - 2 x ln (e) - ln (2)

2 x ln (e) = 2 x

= - 2 x - ln (2)
