simplify ln(1.9+2)-ln(1.9-2)

Solution

simplify

ln (1.9 + 2) - ln (1.9 - 2)

Solution

ln (- 39)

Solution steps

ln (1.9 + 2) - ln (1.9 - 2)

Apply log rule:

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

ln (1.9 + 2) - ln (1.9 - 2) = ln (\frac{2 + 1.9}{1.9 - 2})

= ln (\frac{1.9 + 2}{1.9 - 2})

\frac{1.9 + 2}{1.9 - 2} = - 39

= ln (- 39)
