Schritte zur Lösung

1 0^{x} = 1200

Wende Exponentenregel an

x ln (10) = ln (1200)

Löse

x ln (10) = ln (1200) : x = \frac{ln ( 1200 )}{ln ( 10 )}

x = \frac{ln ( 1200 )}{ln ( 10 )}

- 1 = - 2^{x}

\frac{100}{1 + e ^{- x}} = 4

\frac{100}{1 + e ^{- x}} = 2

5 \cdot 1 0^{x + 2} = 5000

\frac{4 ^{x + 1}}{2 ^{x + 2}} = 128
