ln (x + 7) - 2 ln (x + 1) = ln (16)

x = \frac{- 31 + 385}{32}

Decimal Notation

x = - 0.35558 \dots

Solution steps

ln (x + 7) - 2 ln (x + 1) = ln (16)

Apply log rules

x + 7 = 16 (x + 1)^{2}

Solve

x + 7 = 16 (x + 1)^{2} : x = \frac{- 31 + 385}{32}, x = \frac{- 31 - 385}{32}

x = \frac{- 31 + 385}{32}, x = \frac{- 31 - 385}{32}

Verify Solutions:

x = \frac{- 31 + 385}{32}

True

, x = \frac{- 31 - 385}{32}

False

The solution is

x = \frac{- 31 + 385}{32}

36 = 4 ln (x - 1)
