Wende Exponentenregel an

(2 x + 1) ln (4) = (x + 3) ln (6)

Löse

(2 x + 1) ln (4) = (x + 3) ln (6) : x = \frac{ln ( 54 )}{ln ( \frac{8}{3} )}

x = \frac{ln ( 54 )}{ln ( \frac{8}{3} )}

6 4^{- 2 x - 1} \cdot 8^{4 x} = 1 6^{2 x}

7^{3 x - 2} = 7^{- 2 x + 8}

e^{2 - 4 x} = 9

7^{3 - 5 x} = (\frac{1}{49})^{2 x + 9}

9^{x} = \frac{1}{27}
