log_{2}(x^3-23)=2

Lösung

lo g_{2} (x^{3} - 23) = 2

x = 3

Schritte zur Lösung

lo g_{2} (x^{3} - 23) = 2

Wende die log Regel an

x^{3} - 23 = 4

Löse

x^{3} - 23 = 4 : x = 3

x = 3

lo g_{2} (3 - x) = 4

lo g_{2} (3 - x) = 2

lo g_{10} (lo g_{10} (a)) = - 0.2

1 = lo g_{3} (x)

lo g_{3} (x) - lo g_{3} (9) = 10
