simplify ln((e^x)/(x^7))

Solution

simplify

ln (\frac{e ^{x}}{x ^{7}})

Solution

x - 7 ln (x)

Solution steps

ln (\frac{e ^{x}}{x ^{7}})

Apply log rule:

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

ln (\frac{e ^{x}}{x ^{7}}) = ln (e^{x}) - ln (x^{7})

= ln (e^{x}) - ln (x^{7})

Apply log rule:

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

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

= x ln (e) - ln (x^{7})

Apply log rule:

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

ln (x^{7}) = 7 ln (x)

= x ln (e) - 7 ln (x)

x ln (e) = x

= x - 7 ln (x)
