x = \frac{ln ( 13 )}{ln ( 7 )}

Dezimale

x = 1.31812 \dots

Schritte zur Lösung

7^{x} = 13

Wende Exponentenregel an

x ln (7) = ln (13)

Löse

x ln (7) = ln (13) : x = \frac{ln ( 13 )}{ln ( 7 )}

x = \frac{ln ( 13 )}{ln ( 7 )}

4^{5 x + 1} + 7 = 28

2^{- x} = 5

(e^{4})^{x} (e^{x})^{2} = e^{1} 2

5^{2 x - 1} = 5

3^{x - 2} = 9
