Schritte zur Lösung

9^{x} = 0.9

Wende Exponentenregel an

x ln (9) = ln (0.9)

Löse

x ln (9) = ln (0.9) : x = \frac{ln ( 0.9 )}{2 ln ( 3 )}

x = \frac{ln ( 0.9 )}{2 ln ( 3 )}

so l v e f or x, 5^{2 y} = 3^{2 x + 1}

9^{x + 4} = 2 7^{5 x - 2}

7^{2 x} = 7^{x - 3}

1000000 = 27000 \cdot 131 2^{x}

1 0^{4 x - 8} = 6^{10 x + 3}
