Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions:

Determine the difference quotient \( \frac{f(x+h)-f(x)}{h} \) \( f(x)=2 x^{2}-3 \)

Write the expression as a single logarithm. Express powers as factors. \( \ln \left(\frac{x}{x-5}\right)+\ln \left(\frac{x+5}{x}\right)-\ln \left(x^{2}-25\right) \) \( \ln \left(\frac{x}{x-5}\right)+\ln \left(\frac{x+5}{x}\right)-\ln \left(x^{2}-25\right)=\square \)
