ln (x) + ln (7 x + 1) = 1

x = \frac{- 1 + 1 + 28 e}{14}

Decimal Notation

x = 0.55580 \dots

Solution steps

ln (x) + ln (7 x + 1) = 1

Apply log rules

x (7 x + 1) = e

Solve

x (7 x + 1) = e : x = \frac{- 1 + 1 + 28 e}{14}, x = \frac{- 1 - 1 + 28 e}{14}

x = \frac{- 1 + 1 + 28 e}{14}, x = \frac{- 1 - 1 + 28 e}{14}

Verify Solutions:

x = \frac{- 1 + 1 + 28 e}{14}

True

, x = \frac{- 1 - 1 + 28 e}{14}

False

The solution is

x = \frac{- 1 + 1 + 28 e}{14}

lo g_{5} (n^{2} + 20 n) = 3

lo g_{2} (x - 5) = 2 - lo g_{2} (x - 8)

ln (x^{2}) - 0.7 = 0

0.69 = lo g_{10} (x)

3 ln (2 x) - 4 = 2 ln (2 x)
