Rewrite the Given Expression as a Single Logarithm $\log _{\mathrm{W}}\left(\mathrm{x}^{2}-16\right)-\log _{\mathrm{W}}(\mathrm{x}-4)$

Multiple Choice

Rewrite the given expression as a single logarithm. Assume that all variables are defined in such a way that variable expressions are positive and bases are positive numbers not equal to 1 .
- $\log _{\mathrm{W}}\left(\mathrm{x}^{2}-16\right) -\log _{\mathrm{W}}(\mathrm{x}-4)$

A) $\log _{W}(x+4)$

B) $\frac{\log _{W}\left(x^{2}-16\right) }{\log _{W}(x-4) }$

C) $\log _{W}\left(x^{2}-16\right) (x-4)$

D) $\log _{W}\left[\left(x^{2}-16\right) -(x-4) \right]$
