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

Solution

simplify

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

Solution

ln (x) - 7 x

Solution steps

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

Apply log rule:

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

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

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

Apply log rule:

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

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

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

7 x ln (e) = 7 x

= ln (x) - 7 x
