Numbers written in the form;
A x 10n
Where, 1 ≤ A ≤ 10, are in Standard Form.
When writing a number in standard form:
Step 1: Write the number in the form A. That is, turn the number into a number greater than or equal to 1, and/or less than or equal to 10. This is done by moving the decimal point either to the right or to the left.
Step 2: Multiply the number attained above by 10 for each place moved to the left, and by 
for each place moved to the right.
Step 3: Write the number in the form A x 10n.
Example
Write the following numbers in standard form: (i) 243 876 (ii) 0.000487652
