log_{2}(2x+5)=3

Lösung

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

x = \frac{3}{2}

Dezimale

x = 1.5

Schritte zur Lösung

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

Wende die log Regel an

2 x + 5 = 8

Löse

2 x + 5 = 8 : x = \frac{3}{2}

x = \frac{3}{2}

ln (x) + ln (7 x + 1) = 1

lo g_{5} (n^{2} + 20 n) = 3

ln (x^{2}) - 0.7 = 0

3 ln (2 x) - 4 = 2 ln (2 x)

ln (4 x + 2) = 3
