(iii) 6020000000000000 ,
(iv) 0.00000000837,
(v) 31860000000

Explanation

To express the given numbers in standard form, we will follow these steps for each number:

1. Identify the significant figures in the number.
2. Move the decimal point to the right of the first non-zero digit.
3. Count how many places the decimal point has moved to determine the exponent of 10.
4. Write the number in the form \( a \times 10^n \), where \( a \) is the significant figure and \( n \) is the exponent.

Let's solve each part step by step:
