(1/2)^{x-1}=32

Lösung

(\frac{1}{2})^{x - 1} = 32

x = - 4

Schritte zur Lösung

(\frac{1}{2})^{x - 1} = 32

Wende Exponentenregel an

- (x - 1) = 5

Löse

- (x - 1) = 5 : x = - 4

x = - 4

4^{2 x + 5} = 64

so l v e f or x, e^{z x} = x yz

so l v e f or x, 15 - 0. 5^{x} = - 6

5^{x} = - 5

5^{x} = - 7
