5. 5^{r} = 1.6

r = \frac{ln ( 1.6 )}{ln ( 5.5 )}

Dezimale

r = 0.27570 \dots

Schritte zur Lösung

5. 5^{r} = 1.6

Wende Exponentenregel an

r ln (5.5) = ln (1.6)

Löse

r ln (5.5) = ln (1.6) : r = \frac{ln ( 1.6 )}{ln ( 5.5 )}

r = \frac{ln ( 1.6 )}{ln ( 5.5 )}

2^{2 x} - 29 (2^{x}) - 96 = 0

9^{1 - 2 x} = \frac{1}{2 7 ^{x - 4}}

5 ln (4 - 3^{x}) = 6

so l v e f or y, - 2^{y} + 5 = 7 x

5^{2 x + 3} = 125
