vereinfachen 1/2 ln(x+5)-2ln(x)+ln(y)

Lösung

vereinfachen

\frac{1}{2} ln (x + 5) - 2 ln (x) + ln (y)

ln (\frac{y ( x + 5 ) ^{\frac{1}{2}}}{x ^{2}})

Schritte zur Lösung

\frac{1}{2} ln (x + 5) - 2 ln (x) + ln (y)

Wende die log Regel an:

a lo g_{c} (b) = lo g_{c} (b^{a})

\frac{1}{2} ln (x + 5) = ln ((x + 5)^{\frac{1}{2}})

= ln ((x + 5)^{\frac{1}{2}}) - 2 ln (x) + ln (y)

Wende die log Regel an:

a lo g_{c} (b) = lo g_{c} (b^{a})

2 ln (x) = ln (x^{2})

= ln ((x + 5)^{\frac{1}{2}}) - ln (x^{2}) + ln (y)

Wende die log Regel an:

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

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

= ln (\frac{( x + 5 ) ^{\frac{1}{2}}}{x ^{2}}) + ln (y)

Wende die log Regel an:

lo g_{c} (a) + lo g_{c} (b) = lo g_{c} (ab)

ln (\frac{( x + 5 ) ^{\frac{1}{2}}}{x ^{2}}) + ln (y) = ln (\frac{( x + 5 ) ^{\frac{1}{2}}}{x ^{2}} y)

= ln (\frac{( x + 5 ) ^{\frac{1}{2}}}{x ^{2}} y)
