Solve the equation `4^(x)- 5 xx2^(x) + 4 = 0.`

Explanation

To solve the equation \(4^x - 5 \cdot 2^x + 4 = 0\), we can follow these steps:

### Step 1: Rewrite the equation
We know that \(4^x\) can be expressed as \((2^2)^x = (2^x)^2\). Thus, we can rewrite the equation as:
\[ (2^x)^2 - 5 \cdot 2^x + 4 = 0 \]
