Solving the Equation Lod5(13+x)=log5+8

To solve the equation Lod5(13+x) = log5+8, we can use the properties of logarithms to simplify and solve for the variable x.

First, let's rewrite the equation using the properties of logarithms: Lod5(13+x) = log5+8

We know that log(a) + log(b) = log(ab), so we can rewrite the equation as: log5(13+x) = log5(8)

Now, since the base of the logarithm is the same on both sides, we can drop the logarithm and set the arguments equal to each other: 13 + x = 8

Solving for x: x = 8 - 13 x = -5

Therefore, the solution to the equation Lod5(13+x) = log5+8 is x = -5.
