ln (x) + ln (x + 2) = 4

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

Decimal Notation

x = 6.45641 \dots

Solution steps

ln (x) + ln (x + 2) = 4

Apply log rules

x (x + 2) = e^{4}

Solve

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

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

Verify Solutions:

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

True

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

False

The solution is

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

lo g_{5} (x - 7) = 1 - lo g_{5} (x - 3)

ln (x) + ln (x) = 0

lo g_{x} (9) = \frac{2}{3}

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

ln (x) - ln (\frac{1}{x}) = 2
