vereinfachen ln((sqrt(x))/(e^x(x+3)^2))

Lösung

vereinfachen

ln (\frac{x}{e ^{x} ( x + 3 ) ^{2}})

ln (x) - x - 2 ln (x + 3)

Schritte zur Lösung

ln (\frac{x}{e ^{x} ( x + 3 ) ^{2}})

Wende die log Regel an:

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

ln (\frac{x}{e ^{x} ( x + 3 ) ^{2}}) = ln (x) - ln (e^{x} (x + 3)^{2})

= ln (x) - ln (e^{x} (x + 3)^{2})

Wende die log Regel an:

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

ln (e^{x} (x + 3)^{2}) = ln (e^{x}) + ln ((x + 3)^{2})

= ln (x) - (ln (e^{x}) + ln ((x + 3)^{2}))

Wende die log Regel an:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

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

= ln (x) - (x ln (e) + ln ((x + 3)^{2}))

Wende die log Regel an:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln ((x + 3)^{2}) = 2 ln (x + 3)

= ln (x) - (x ln (e) + 2 ln (x + 3))

x ln (e) = x

= ln (x) - (x + 2 ln (x + 3))

- (x + 2 ln (x + 3)) : - x - 2 ln (x + 3)

= ln (x) - x - 2 ln (x + 3)
