x = 3, x = - 5

Schritte zur Lösung

8^{(x^{2} + 2 x - 15)} = 1

Wende Exponentenregel an

(x^{2} + 2 x - 15) ln (8) = ln (1)

Löse

(x^{2} + 2 x - 15) ln (8) = ln (1) : x = 3, x = - 5

x = 3, x = - 5

\frac{2 ^{x} - 2 ^{- x}}{3} = 4

9^{x} = 1

4^{x} + 4^{x - 1} + 4^{x - 2} = 336

e^{2 x} - 2 e^{x} = 0

e^{2 x} - 2 e^{x} = 3
