3^{x-1}= 3/(sqrt(27))

Lösung

3^{x - 1} = \frac{3}{27}

x = \frac{1}{2}

Dezimale

x = 0.5

Schritte zur Lösung

3^{x - 1} = \frac{3}{27}

Wende Exponentenregel an

x - 1 = - \frac{1}{2}

Löse

x - 1 = - \frac{1}{2} : x = \frac{1}{2}

x = \frac{1}{2}

8^{x - 3} = 4^{3 x - 1}

e^{3 x - 2} = 1

so l v e f or x, e^{- 0.78 x} = 0.03

5^{x + 5} = 125

0. 1^{x} = 100
