simplify ln((x^2-1)/(x^7))

Solution

simplify

ln (\frac{x ^{2} - 1}{x ^{7}})

Solution

ln (x^{2} - 1) - 7 ln (x)

Solution steps

ln (\frac{x ^{2} - 1}{x ^{7}})

Apply log rule:

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

ln (\frac{x ^{2} - 1}{x ^{7}}) = ln (x^{2} - 1) - ln (x^{7})

= ln (x^{2} - 1) - ln (x^{7})

Apply log rule:

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

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

= ln (x^{2} - 1) - 7 ln (x)
