simplify ln(2r)-ln(r)

Solution

simplify

ln (2 r) - ln (r)

Solution

ln (2)

+1

Decimal Notation

0.69314 \dots

Solution steps

ln (2 r) - ln (r)

Apply log rule:

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

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

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

Cancel the common factor:

r

= ln (2)
