Express the following numbers in standard form.
`(i) 0.0000000000085`
`(ii)0.00000000000942`
`(iii)6020000000000000`
`(iv)0.00000000837`
`(v)31860000000`

Explanation

To express the given numbers in standard form, we follow the rule that a number in standard form is expressed as \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.

Let's solve each part step-by-step:

### (i) \( 0.0000000000085 \)

1. **Identify the significant figures**: The significant figure here is \( 8.5 \).
2. **Count the decimal places**: Move the decimal point 12 places to the right to get \( 8.5 \).
