log_{2}(x)=-7

Lösung

lo g_{2} (x) = - 7

x = \frac{1}{128}

Dezimale

x = 0.0078125

Schritte zur Lösung

lo g_{2} (x) = - 7

Wende die log Regel an

x = \frac{1}{128}

2 ln (x) + ln (x + 1) = ln (2)

lo g_{2} (x) = 20

ln (d) = ln (x) + 1

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

lo g_{9} (8 x - 15) = 0
