Schritte zur Lösung

3^{x} = 4.6

Wende Exponentenregel an

x ln (3) = ln (4.6)

Löse

x ln (3) = ln (4.6) : x = \frac{ln ( 4.6 )}{ln ( 3 )}

x = \frac{ln ( 4.6 )}{ln ( 3 )}

8 \cdot 2^{2 x} + 7 \cdot 2^{x} - 1 = 0

2^{x + 1} + 2^{x + 2} + 2^{x + 3} = 224

3^{x} = 78

2^{- x^{2}} = 5

6^{3 x - 7} = 3 6^{x - 1}
