log_{10}(t^2-2)=4

Lösung

lo g_{10} (t^{2} - 2) = 4

t = 10002, t = - 10002

Dezimale

t = 100.00999 \dots, t = - 100.00999 \dots

Schritte zur Lösung

lo g_{10} (t^{2} - 2) = 4

Wende die log Regel an

t^{2} - 2 = 10000

Löse

t^{2} - 2 = 10000 : t = 10002, t = - 10002

t = 10002, t = - 10002

ln (x) + ln (8 x) = 9

20 \cdot lo g_{10} (X) = 20

lo g_{10} (2 x) = 1.6

lo g_{2} (2 x + 2) = 0

lo g_{2} (2 x + 2) = 1
