x = 0.73248 \dots

Schritte zur Lösung

9^{x} = 5

Wende Exponentenregel an

x ln (9) = ln (5)

Löse

x ln (9) = ln (5) : x = \frac{ln ( 5 )}{2 ln ( 3 )}

x = \frac{ln ( 5 )}{2 ln ( 3 )}

8 (8^{2 x}) + 23 (8^{x}) - 3 = 0

2^{2 x - 1} = \frac{1}{5 ^{2 x - 1}}

1 5^{- 9 x} = 5

so l v e f or n, 9 + 3^{n + 2} = m

5^{x - 2} = 2
