log_{3}(7-x)=2log_{3}(7)

lo g_{3} (7 - x) = 2 lo g_{3} (7)

x = - 42

Solution steps

lo g_{3} (7 - x) = 2 lo g_{3} (7)

Apply log rules

7 - x = 49

Solve

7 - x = 49 : x = - 42

x = - 42

Verify Solutions:

x = - 42

True

The solution is

x = - 42

ln (x - 3) - ln (x - 2) = 5

lo g_{x + 4} (3 x^{2} - 2 x + 16) = 2

lo g_{5} (x + 6) = 2

lo g_{10} (x) = 10.89

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