log_{7}(13x+20)=log_{7}(72)

lo g_{7} (13 x + 20) = lo g_{7} (72)

x = 4

Solution steps

lo g_{7} (13 x + 20) = lo g_{7} (72)

Apply log rules

13 x + 20 = 72

Solve

13 x + 20 = 72 : x = 4

x = 4

Verify Solutions:

x = 4

True

The solution is

x = 4

n = lo g_{2} (n)

lo g_{10} (x y) = lo g_{10} (x y)

a, ln (\frac{a}{b}) = 5 g

2 ln (3 x) = - 2

6 lo g_{x} (2) + lo g_{2} (x) - 5 = 0
