Transcript text: Use algebraic procedures to find the exact solution
\[
\left(\frac{5}{2}\right)^{x}=\frac{125}{8}
\]
Solution
Solution Steps
To solve the equation \(\left(\frac{5}{2}\right)^{x}=\frac{125}{8}\), we can use logarithms to isolate \(x\). By taking the natural logarithm (or any logarithm) on both sides, we can then solve for \(x\).
Step 1: Rewrite the Equation
We start with the equation:
\[
\left(\frac{5}{2}\right)^{x} = \frac{125}{8}
\]
Step 2: Express the Right Side in Terms of the Base
We can express \(\frac{125}{8}\) as:
\[
\frac{125}{8} = \frac{5^3}{2^3} = \left(\frac{5}{2}\right)^{3}
\]
Step 3: Set the Exponents Equal
Since the bases are the same, we can set the exponents equal to each other:
\[
x = 3
\]
Final Answer
Thus, the solution to the equation is:
\[
\boxed{x = 3}
\]
