simplify ln(a-4)+9ln(a)

Solution

simplify

ln (a - 4) + 9 ln (a)

Solution

ln ((a - 4) a^{9})

Solution steps

ln (a - 4) + 9 ln (a)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

9 ln (a) = ln (a^{9})

= ln (a - 4) + ln (a^{9})

Apply log rule:

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

ln (a - 4) + ln (a^{9}) = ln (a^{9} (a - 4))

= ln ((a - 4) a^{9})
