Lösung

200 = 4^{x}

x = \frac{ln ( 200 )}{2 ln ( 2 )}

Dezimale

x = 3.82192 \dots

Schritte zur Lösung

200 = 4^{x}

Wende Exponentenregel an

ln (200) = x ln (4)

Löse

ln (200) = x ln (4) : x = \frac{ln ( 200 )}{2 ln ( 2 )}

x = \frac{ln ( 200 )}{2 ln ( 2 )}

8^{4 x} = \frac{1}{2 2}

200 = 4^{t}

B (t) = 2190 \cdot e^{- 0.3 t}

so l v e f or z, 0 = e^{2 x + 2 y + z}

5^{x + 1} = 625
