Lösung

1 2^{b} = 3

b = \frac{ln ( 3 )}{ln ( 12 )}

Dezimale

b = 0.44211 \dots

Schritte zur Lösung

1 2^{b} = 3

Wende Exponentenregel an

b ln (12) = ln (3)

Löse

b ln (12) = ln (3) : b = \frac{ln ( 3 )}{ln ( 12 )}

b = \frac{ln ( 3 )}{ln ( 12 )}

2^{n} = 6

230 \cdot 1.01 5^{t} = 325

0 = 2^{x - 3} - 1

e^{0.5 x} = 3

7^{5 x + 4} = 56
