log_{10}(3x+7)=2

Lösung

lo g_{10} (3 x + 7) = 2

x = 31

Schritte zur Lösung

lo g_{10} (3 x + 7) = 2

Wende die log Regel an

3 x + 7 = 100

Löse

3 x + 7 = 100 : x = 31

x = 31

0 = x ln (3 x - 5)

ln (3 x - 5) = 6

so l v e f or y, y = ln (3 x + 4 y)

lo g_{4} (2 x - 6) = 3

lo g_{10} (8 x) - lo g_{10} (1 + x) = 2
