log_{10}(x)-log_{10}(x+3)=-1

lo g_{10} (x) - lo g_{10} (x + 3) = - 1

x = \frac{1}{3}

Decimal

x = 0.33333 \dots

Solution steps

lo g_{10} (x) - lo g_{10} (x + 3) = - 1

Add

lo g_{10} (x + 3)

to both sides

lo g_{10} (x) - lo g_{10} (x + 3) + lo g_{10} (x + 3) = - 1 + lo g_{10} (x + 3)

Simplify

lo g_{10} (x) = - 1 + lo g_{10} (x + 3)

Apply log rules

x \cdot 10 = x + 3

Solve

x \cdot 10 = x + 3 : x = \frac{1}{3}

x = \frac{1}{3}

Verify Solutions:

x = \frac{1}{3}

True

The solution is

x = \frac{1}{3}

lo g_{100000} (x) = 5^{- 1}

lo g_{x} (8) 2 = \frac{7}{4}

lo g_{10} (x) = 1 - lo g_{10} (30)

ln (x) = 354.08

ln (x) + c
