simplify-ln(10/20)

simplify

- ln (\frac{10}{20})

- ln (10) + ln (20)

Solution steps

- ln (\frac{10}{20})

Apply log rule:

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

ln (\frac{10}{20}) = ln (10) - ln (20)

= - (ln (10) - ln (20))

Distribute parentheses

= - (ln (10)) - (- ln (20))

Apply minus-plus rules

- (- a) = a, - (a) = - a

= - ln (10) + ln (20)

ln (\frac{ln ( x ^{2} )}{4 x})

ln (\frac{( 48 ) - ( 9 )}{( 70 ) - ( 9 )})

ln (\frac{658405861}{2405861})

ln (2) - ln (\frac{3}{3})

ln (7) + ln (x) + 5 ln (y) - 2 ln (x)
