2^x=38

Lösung

2^{x} = 38

x = \frac{ln ( 38 )}{ln ( 2 )}

Dezimale

x = 5.24792 \dots

Schritte zur Lösung

2^{x} = 38

Wende Exponentenregel an

x ln (2) = ln (38)

Löse

x ln (2) = ln (38) : x = \frac{ln ( 38 )}{ln ( 2 )}

x = \frac{ln ( 38 )}{ln ( 2 )}

e^{6 x} = 7

2^{n} = 128

2 7^{1 - x} = \frac{1}{81}

e^{2 x} - e^{x} - 72 = 0

so l v e f or y, \frac{9 ^{x - 1}}{3 ^{y + 2}} = 81
