Solution steps

(0.9) ln (5500) + (0.1) ln (4500)

Apply log rule:

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

(0.9) ln (5500) = ln (550 0^{(0.9)})

= ln (550 0^{(0.9)}) + (0.1) ln (4500)

Apply log rule:

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

(0.1) ln (4500) = ln (450 0^{(0.1)})

= ln (550 0^{(0.9)}) + ln (450 0^{(0.1)})

Apply log rule:

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

ln (550 0^{(0.9)}) + ln (450 0^{(0.1)}) = ln (550 0^{0.9} \cdot 450 0^{0.1})

= ln (550 0^{0.9} \cdot 450 0^{0.1})

550 0^{(0.9)} \cdot 450 0^{(0.1)} = 5390.73113 \dots

= ln (5390.73113 \dots)

ln (\frac{2 y}{x})

ln (80) - ln (180)

ln (2) ln (3) - ln (45) + 2 ln (5)

ln (\frac{2 ^{- 4}}{3 ^{1} 5 ^{4}})

- ln (\frac{- x}{A \cdot k})
