simplify ln(a/2)-ln(a)

Solution

simplify

ln (\frac{a}{2}) - ln (a)

Solution

- ln (2)

+1

Decimal Notation

- 0.69314 \dots

Solution steps

ln (\frac{a}{2}) - ln (a)

Apply log rule:

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

ln (\frac{a}{2}) - ln (a) = ln (\frac{\frac{a}{2}}{a})

= ln (\frac{\frac{a}{2}}{a})

\frac{\frac{a}{2}}{a} = \frac{1}{2}

= ln (\frac{1}{2})

Apply log rule:

lo g_{a} (\frac{1}{x}) = - lo g_{a} (x)

= - ln (2)
