simplify ln(-1)-ln(2-sqrt(5))

Solution

simplify

ln (- 1) - ln (2 - 5)

Solution

ln (5 + 2)

+1

Decimal Notation

1.44363 \dots

Solution steps

ln (- 1) - ln (2 - 5)

Apply log rule:

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

ln (- 1) - ln (2 - 5) = ln (\frac{- 1}{2 - 5})

= ln (\frac{- 1}{2 - 5})

\frac{- 1}{2 - 5} = 5 + 2

= ln (5 + 2)
