log_{3}(x-sqrt(x-1))=1

Lösung

lo g_{3} (x - x - 1) = 1

x = 5

Schritte zur Lösung

lo g_{3} (x - x - 1) = 1

Wende die log Regel an

x - x - 1 = 3

Löse

x - x - 1 = 3 : x = 5

x = 5

lo g_{4} (2 x - 3) + lo g_{4} (5 - x) = 2

so l v e f or x, ln (x + 4) = 4

lo g_{10} (\frac{1}{x}) = 8.78

ln (x) + x = 4

4 = lo g_{10} (3 x)
