2^{x} = 125

x = \frac{3 ln ( 5 )}{ln ( 2 )}

Dezimale

x = 6.96578 \dots

Schritte zur Lösung

2^{x} = 125

Wende Exponentenregel an

x ln (2) = ln (125)

Löse

x ln (2) = ln (125) : x = \frac{3 ln ( 5 )}{ln ( 2 )}

x = \frac{3 ln ( 5 )}{ln ( 2 )}

7^{9 x + 7} = 2

so l v e f or x, y = 3^{x}

so l v e f or x, 7^{x - 1} = e^{y}

5^{2 x - 3} = 7^{x + 1}

21 6^{x + 2} = 7776
