Answer 2

To solve the equation "log(9+x) base 3 = log(5) base 3," we can use the properties of logarithms. In this case, since both logarithms have the same base (which is 3), we can set their arguments equal to each other:

log₃(9 + x) = log₃(5)

Now, according to the logarithm property, if logₐ(b) = logₐ(c), then b = c. Applying this property to our equation:

9 + x = 5

Now, we can solve for x:

x = 5 - 9 x = -4

So, the value of x that satisfies the equation is x = -4.
