Question

when $1.250 \times 10^{-2}$ is correctly converted to its standard form, the number becomes ______
0.01250
0.1250
1.250
12.50
125.0

Explanation:

Step1: Recall scientific notation to standard form

To convert \(a\times10^{n}\) to standard form, if \(n\) is negative, we move the decimal point \(|n|\) places to the left. Here, the number is \(1.250\times10^{- 2}\), so \(n=-2\), and we move the decimal point 2 places to the left.

Step2: Perform the conversion

Starting with \(1.250\), moving the decimal point 2 places to the left: \(1.250
ightarrow0.01250\) (we add a zero before the 1 when moving the decimal point past the units place).

Answer:

0.01250
