log_{10}(x+3)=2

Lösung

lo g_{10} (x + 3) = 2

x = 97

Schritte zur Lösung

lo g_{10} (x + 3) = 2

Wende die log Regel an

x + 3 = 100

Löse

x + 3 = 100 : x = 97

x = 97

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

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

so l v e f or x, 2 = - lo g_{10} (x)

- 1 - 5 \cdot ln (x) = 1

lo g_{2} (k + 2) - lo g_{2} (3 - k) = - 2
