0=log_{1/4}(-x+4)

Lösung

0 = lo g_{\frac{1}{4}} (- x + 4)

x = 3

Schritte zur Lösung

0 = lo g_{\frac{1}{4}} (- x + 4)

Wende die log Regel an

1 = - x + 4

Löse

1 = - x + 4 : x = 3

x = 3

lo g_{3} (x + 1) - lo g_{3} (x - 2) = 2

- 1 = ln (8 x)

ln (5 x) + 4 = ln (3 x + 4)

lo g_{3} (5 x + 3) = 5

so l v e f or x, ln (x + y) = 5
