What is the correct answer when you convert the number, 0.0472 into scientific notation?

47.2 × 10
0.472 × 10 -3
472
4.72× 10 2
4.72 × 10 -2

To convert the number \(0.0472\) into scientific notation, follow these steps:

1. **Identify the significant figures**: The significant figures in \(0.0472\) are \(4.72\).
2. **Determine the decimal place movement**: The decimal needs to be moved 2 places to the right to convert \(0.0472\) into \(4.72\).
3. **Determine the exponent**: Since the decimal was moved 2 places to the right, the exponent is \(-2\).

So, \(0.0472\) in scientific notation is \(4.72 \times 10^{-2}\).

The correct answer is:

**4.72 × 10⁻²**
