ln (x + 1) + ln (x) = 3

x = \frac{- 1 + 1 + 4 e ^{3}}{2}

Solution steps

ln (x + 1) + ln (x) = 3

Apply log rules

(x + 1) x = e^{3}

Solve

(x + 1) x = e^{3} : x = \frac{- 1 + 1 + 4 e ^{3}}{2}, x = \frac{- 1 - 1 + 4 e ^{3}}{2}

x = \frac{- 1 + 1 + 4 e ^{3}}{2}, x = \frac{- 1 - 1 + 4 e ^{3}}{2}

Verify Solutions:

x = \frac{- 1 + 1 + 4 e ^{3}}{2}

True

, x = \frac{- 1 - 1 + 4 e ^{3}}{2}

False

The solution is

x = \frac{- 1 + 1 + 4 e ^{3}}{2}

ln (x + 1) + ln (x) = 0

x, y = 2 ln (x)

50 = 15.343 ln (x) + 73.921

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

2 ln (x - 5) = 6
