Schritte zur Lösung

\frac{3}{16} [1 \cdot ln (1) + 4 ln (\frac{4}{3}) + 5 ln (\frac{5}{3}) + 2 ln (2)]

Wende die log Regel an:

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

4 ln (\frac{4}{3}) = ln ((\frac{4}{3})^{4})

= \frac{3}{16} [1 \cdot ln (1) + 5 ln (\frac{5}{3}) + 2 ln (2) + ln ((\frac{4}{3})^{4})]

Wende die log Regel an:

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

5 ln (\frac{5}{3}) = ln ((\frac{5}{3})^{5})

= \frac{3}{16} [1 \cdot ln (1) + 2 ln (2) + ln ((\frac{4}{3})^{4}) + ln ((\frac{5}{3})^{5})]

Wende die log Regel an:

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

ln ((\frac{4}{3})^{4}) + ln ((\frac{5}{3})^{5}) = ln ((\frac{5}{3})^{5} (\frac{4}{3})^{4})

= \frac{3}{16} [1 \cdot ln (1) + 2 ln (2) + ln ((\frac{5}{3})^{5} (\frac{4}{3})^{4})]

(\frac{4}{3})^{4} (\frac{5}{3})^{5} = \frac{800000}{19683}

= \frac{3}{16} [1 \cdot ln (1) + ln (\frac{800000}{19683}) + 2 ln (2)]

Wende die log Regel an:

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

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

= \frac{3}{16} [1 \cdot ln (1) + ln (2^{2}) + ln (\frac{800000}{19683})]

Wende die log Regel an:

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

ln (\frac{800000}{19683}) + ln (2^{2}) = ln (2^{2} \cdot \frac{800000}{19683})

= \frac{3}{16} [1 \cdot ln (1) + ln (2^{2} \cdot \frac{800000}{19683})]

\frac{800000}{19683} \cdot 2^{2} = \frac{3200000}{19683}

= \frac{3}{16} [1 \cdot ln (1) + ln (\frac{3200000}{19683})]

1 \cdot ln (1) = 0

= \frac{3}{16} (ln (\frac{3200000}{19683}) + 0)

0 + ln (\frac{3200000}{19683}) = ln (\frac{3200000}{19683})

= \frac{3}{16} ln (\frac{3200000}{19683})
