simplify ln(1/(1-20))

Solution

simplify

ln (\frac{1}{1 - 20})

Solution

- ln (- 19)

Solution steps

ln (\frac{1}{1 - 20})

Apply log rule:

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

ln (\frac{1}{1 - 20}) = ln (1) - ln (1 - 20)

= ln (1) - ln (1 - 20)

Apply log rule:

lo g_{a} (1) = 0

= 0 - ln (1 - 20)

Subtract the numbers:

1 - 20 = - 19

= 0 - ln (- 19)

0 - ln (- 19) = - ln (- 19)

= - ln (- 19)
