Write the number in decimal notation.

2 × 104 + 0 × 103 + 3 × 102 + 5 × 101 + 7 × 100

To convert the expression \(2 \times 10^4 + 0 \times 10^3 + 3 \times 10^2 + 5 \times 10^1 + 7 \times 10^0\) into decimal notation, we calculate each term individually:

1. \(2 \times 10^4 = 20000\)
2. \(0 \times 10^3 = 0\)
3. \(3 \times 10^2 = 300\)
4. \(5 \times 10^1 = 50\)
5. \(7 \times 10^0 = 7\)

Now, we add these values together:

\[
20000 + 0 + 300 + 50 + 7 = 20357
\]

Thus, the number in decimal notation is **20357**.
