log_{2}(x+4)=3

Lösung

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

x = 4

Schritte zur Lösung

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

Wende die log Regel an

x + 4 = 8

Löse

x + 4 = 8 : x = 4

x = 4

lo g_{6} ((5 x - 9)^{2}) = 4

lo g_{x} (5) = 3

so l v e f or x, ln (x) - ln (x + 2) = 1

lo g_{10} (x) + ln (x) = 1

5 = - lo g_{10} (x)
