log_{5}(x^2)=-2

Lösung

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

x = \frac{1}{5}, x = - \frac{1}{5}

Dezimale

x = 0.2, x = - 0.2

Schritte zur Lösung

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

Wende die log Regel an

x^{2} = \frac{1}{25}

Löse

x^{2} = \frac{1}{25} : x = \frac{1}{5}, x = - \frac{1}{5}

x = \frac{1}{5}, x = - \frac{1}{5}

ln (x - 1) = lo g_{81} (3)

ln (x^{2}) - 1 = 3

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

0.456 = ln (x^{3})

lo g_{10} (5 x - 1) = 0.6
