2^{4x}=8^{7-x}

Lösung

2^{4 x} = 8^{7 - x}

x = 3

Schritte zur Lösung

2^{4 x} = 8^{7 - x}

Wende Exponentenregel an

4 x = 3 (7 - x)

Löse

4 x = 3 (7 - x) : x = 3

x = 3

so l v e f or x, 7^{x} = e^{t}

(\frac{5}{2})^{3 x + 4} = (\frac{2}{5})^{4 x + 10}

9^{x} = - 9

2^{x} = 40

so l v e f or c, p (b^{c}) = 0.7
