10^{14}=(10^{-9})(10^x)

Lösung

1 0^{14} = (1 0^{- 9}) (1 0^{x})

x = 23

Schritte zur Lösung

1 0^{14} = (1 0^{- 9}) (1 0^{x})

Wende Exponentenregel an

14 = x - 9

Löse

14 = x - 9 : x = 23

x = 23

77 = 1 5^{x}

e^{(l n (0.4)) t} = 0.7

so l v e f or n, 128 = 2^{n - 1}

e^{x + 3} = 2

(\frac{1}{2})^{x} = - 4
