Solve. See the Concept Check in this section. Let \(f(x)=\log _{5} x .\) Then \(g(x)=5^{x}\) is the inverse of \(f(x)\) The ordered pair \((2,25)\) is a solution of the function \(g(x)\). a. Write this solution using function notation. b. Write an ordered pair that we know to be a solution of \(f(x)\) c. Use the answer to part b and write the solution using function notation.
Solve. See Example 4. $$ \log _{2 / 3} x=2 $$
Solve. See Example 4. $$ 5^{\log _{5} 7}=x $$
If \(x=-2, y=0,\) and \(z=3,\) find the value of each expression. See Section 1.3 $$ \frac{x^{2}-y+2 z}{3 x} $$
CONCEPT EXTENSIONS. Without using a calculator, explain which of \(\log 50^{-1}\) or \(\ln 50^{-1}\) must be larger and why.
