Schritte zur Lösung

1 2^{x - 8} = 18

Wende Exponentenregel an

(x - 8) ln (12) = ln (18)

Löse

(x - 8) ln (12) = ln (18) : x = \frac{ln ( 18 )}{ln ( 12 )} + 8

x = \frac{ln ( 18 )}{ln ( 12 )} + 8

\frac{e ^{2 x + 3}}{e ^{3}} = 5

2 e^{- x} = 3

6 4^{x} = 4

2^{3} \cdot 2^{4} = 2^{p}

1 6^{x} = 4^{x + 2} + 1
