2^{x+3}*3^{x+4}=18

Lösung

2^{x + 3} \cdot 3^{x + 4} = 18

x = - 2

Schritte zur Lösung

2^{x + 3} \cdot 3^{x + 4} = 18

Wende Exponentenregel an

x + 3 = 1

Löse

x + 3 = 1 : x = - 2

x = - 2

(\frac{1}{2})^{x} = 64

so l v e f or x, 2^{m} - 2^{x} = 2^{4} \cdot 7

5^{x} - 4 = 5^{10}

16 \cdot 4^{x + 2} - 16 \cdot 2^{x + 1} + 1 = 0

1 1^{- 6 y} = 6
