3^{2x}=3^{x+5}

Lösung

3^{2 x} = 3^{x + 5}

x = 5

Schritte zur Lösung

3^{2 x} = 3^{x + 5}

Wende Exponentenregel an

2 x = x + 5

Löse

2 x = x + 5 : x = 5

x = 5

e^{- 0.2 t} = 121

50 = 73 + (36 - 73) e^{- k (45)}

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

16 = 2^{x - 3}

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