Transcript text: Solve the exponential equation by expressing each side as a power of the
\[
8^{x}=16
\]
The solution set is $\square$ (Simplify your answer.)
Solution
Solution Steps
Step 1: Rewrite the Equation
We start with the exponential equation \(8^x = 16\). We express both sides as powers of \(2\):
\[
8 = 2^3 \quad \text{and} \quad 16 = 2^4
\]
Thus, we can rewrite the equation as:
\[
(2^3)^x = 2^4
\]
Step 2: Apply the Power of a Power Property
Using the power of a power property, we simplify the left side:
\[
2^{3x} = 2^4
\]
Step 3: Set the Exponents Equal
Since the bases are the same, we can set the exponents equal to each other:
\[
3x = 4
\]
Step 4: Solve for \(x\)
To find \(x\), we divide both sides by \(3\):
\[
x = \frac{4}{3}
\]
