log_{2}(x^2+3x-2)=3

Lösung

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

x = 2, x = - 5

Schritte zur Lösung

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

Wende die log Regel an

x^{2} + 3 x - 2 = 8

Löse

x^{2} + 3 x - 2 = 8 : x = 2, x = - 5

x = 2, x = - 5

lo g_{2} (5 x - 1) = 2

lo g_{8} (x) - lo g_{x} (64) = 1

\frac{ln ( x )}{x} = 3

lo g_{10} (7 - 2 x) = - 1

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