Answer 1

`log_(25)( (v)/( √(w) ) ) =`

`log_(25)(v) - log_(25)( √(w) ) =`

`log_(25)(v) - (1)/(2) log_(25)(w) =`

`(2 log_(25)(v) - log_(25)(w) )/(2)`

`ln( \sqrt{ \frac{b}{ {c}^(7) a} } ) = (1)/(2) ln( \frac{b}{ {c}^(7)a } ) =`

`(1)/(2) ( ln(b) - ln( {c}^(7)a ) ) =`

`(1)/(2) ( ln(b) - ( ln( {c} ^(7)) + ln(a) ) )`

`(1)/(2) ( ln(b) - 7 ln(c) - ln(a) )`

`log_(k)( { \frac{ {a}^(7) }{yv} })^{ (1)/(5) } = (1)/(5) log_(k)( \frac{ {a}^(7) }{yv} ) =`

`(1)/(5) ( log_(k)( {a}^(7)) - log_(k)(yv) )`

`(1)/(5) (7 log_(k)(a) - log_(k)(y) - log_(k)(v) )`
