lo g_{10} (3 x) + lo g_{10} (x + 2) = 0

x = \frac{- 3 + 2 3}{3}

Solution steps

lo g_{10} (3 x) + lo g_{10} (x + 2) = 0

Apply log rules

3 x (x + 2) = 1

Solve

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

x = \frac{- 3 + 2 3}{3}, x = - \frac{3 + 2}{3}

Verify Solutions:

x = \frac{- 3 + 2 3}{3}

True

, x = - \frac{3 + 2}{3}

False

The solution is

x = \frac{- 3 + 2 3}{3}

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

lo g_{10} (3 x) + lo g_{10} (x + 2) = 7

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

lo g_{x} (2) + lo g_{2} (x) = 0

x, ln (3 x - 13) = 3
