Schritte zur Lösung

3^{2 x + 5} = 4

Wende Exponentenregel an

(2 x + 5) ln (3) = ln (4)

Löse

(2 x + 5) ln (3) = ln (4) : x = \frac{2 ln ( 2 ) - 5 ln ( 3 )}{2 ln ( 3 )}

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

so l v e f or y, z x + e^{zy} = x

so l v e f or x, f = m \cdot 6^{- x}

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

lo g_{3} (8 1^{x}) = 16

3 e^{5 x} = 10
