log_{3}(30^x-9)=0

Lösung

lo g_{3} (3 0^{x} - 9) = 0

Lösung

x = \frac{ln ( 10 )}{ln ( 30 )}

+1

Dezimale

x = 0.67699 \dots

Schritte zur Lösung

lo g_{3} (3 0^{x} - 9) = 0

Wende die log Regel an

3 0^{x} - 9 = 1

Löse

3 0^{x} - 9 = 1 : x = \frac{ln ( 10 )}{ln ( 30 )}

x = \frac{ln ( 10 )}{ln ( 30 )}
