The standard form of \(1.2 \times 10^4\) can be calculated by moving the decimal point in \(1.2\) four places to the right, since the exponent is positive.
Starting with \(1.2\):
- Moving the decimal one place gives \(12.0\) (or just \(12\)).
- Moving it another place gives \(120\).
- Moving it another place gives \(1200\).
- Moving it a final fourth place gives \(12000\).
Therefore, \(1.2 \times 10^4 = 12000\).
The correct answer is \(12,000\).
