2log_{7}(sqrt(x-1))=0

2 lo g_{7} (x - 1) = 0

x = 2

Solution steps

2 lo g_{7} (x - 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

lo g_{7} (x - 1) = 0

Solve

lo g_{7} (x - 1) = 0 : x = 2

Verify Solutions:

x = 2

True

The solution is

x = 2

x, 5 x + 3 ln (x - 4) = 25

10 lo g_{10} (\frac{x}{20}) = 5

lo g_{a} (16) = \frac{1}{2}

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

ln (x) + ln (x - 2) = ln (2 x)
