Use the properties of logarithms to evaluate the expression.

5 log5 (7x)

Evaluate the expression? What is x then?

then how do i simplify it?

The expression 5 log5 (7x) is simplified.

To evaluate the expression 5 log5 (7x) using the properties of logarithms, we can start by applying the property that states log(base a) (b) = 1 / log(base b) (a).

In this case, the base of the logarithm is 5. Therefore, we have:

5 log5 (7x) = 5 * (1 / log(7x) (5))

Next, we can apply another property, which states that log(base a) (a) = 1.

So, we can write it as:

5 * (1 / log(7x) (5)) = 5 * (1 / 1)

Which simplifies to:

5 * (1 / 1) = 5

Therefore, the expression 5 log5 (7x) simplifies to 5.
