검증된 단계별 안내1
Identify the given number in scientific notation: \(1.2 \times 10^{5}\).
Understand that \$10^{5}$ means moving the decimal point 5 places to the right because the exponent is positive.
Start with the number 1.2 and move the decimal point 5 places to the right, adding zeros as needed.
After moving the decimal point 5 places, write down the resulting number without the decimal point.
The final number is the standard decimal form of \(1.2 \times 10^{5}\).
