log_{1/2}(7-8x)=-2

Lösung

lo g_{\frac{1}{2}} (7 - 8 x) = - 2

x = \frac{3}{8}

Dezimale

x = 0.375

Schritte zur Lösung

lo g_{\frac{1}{2}} (7 - 8 x) = - 2

Wende die log Regel an

7 - 8 x = 4

Löse

7 - 8 x = 4 : x = \frac{3}{8}

x = \frac{3}{8}

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

lo g_{3} (4 x + 8) - 7 = - 3

(ln (x) + 1) = 0

20 - ln (3 - x) = 0

ln (- x) = - 1
