ln (x) + ln (x - 10) = 1

x = \frac{10 + 100 + 4 e}{2}

Decimal Notation

x = 10.26481 \dots

Solution steps

ln (x) + ln (x - 10) = 1

Apply log rules

x (x - 10) = e

Solve

x (x - 10) = e : x = \frac{10 + 100 + 4 e}{2}, x = \frac{10 - 100 + 4 e}{2}

x = \frac{10 + 100 + 4 e}{2}, x = \frac{10 - 100 + 4 e}{2}

Verify Solutions:

x = \frac{10 + 100 + 4 e}{2}

True

, x = \frac{10 - 100 + 4 e}{2}

False

The solution is

x = \frac{10 + 100 + 4 e}{2}

lo g_{10} (2 x + 4) = 2, x

- ln (x) + 2 = 0

2 + lo g_{3} (2 x + 5) - lo g_{3} (x) = 4

lo g_{2} (5 - 2 x) = 3 + lo g_{2} (x + 1)

lo g_{x + 6} (2 x^{2} + 3 x) = 2
