Write the order of magnitude of the given measurments:
(i) 57
(ii) 1001
(iii) 879000
(iv) `0.04`
(v) 38750000
(vi) `0.00000681`.

Explanation

To find the order of magnitude for each of the given measurements, we will express each number in the form \( x \times 10^y \), where \( x \) is between 0.5 and 5, inclusive. The value of \( y \) will then represent the order of magnitude.

Let's go through each measurement step by step:

### (i) 57
1. **Convert to scientific notation**: We can express 57 as \( 5.7 \times 10^1 \).
2. **Identify \( y \)**: Here, \( y = 1 \).
3. **Order of magnitude**: The order of magnitude is **1**.
