expand ln(xy^8z^9)

Solution

expand

ln (x y^{8} z^{9})

Solution

ln (x) + 8 ln (y) + 9 ln (z)

Solution steps

ln (x y^{8} z^{9})

Apply log rule:

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

ln (x y^{8} z^{9}) = ln (x) + ln (y^{8}) + ln (z^{9})

= ln (x) + ln (y^{8}) + ln (z^{9})

Apply log rule:

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

ln (y^{8}) = 8 ln (y)

= ln (x) + 8 ln (y) + ln (z^{9})

Apply log rule:

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

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

= ln (x) + 8 ln (y) + 9 ln (z)
