standard form

|
Standard Form is a convenient way of writing very large or very small numbers. It is written in the form a x 10 raised to the power of 'n' where ‘a’ is a number between 1 and 9.
For large numbers the power of ‘n’ will be positive. For numbers smaller than 1, the power of ‘n’ will be negative. To change a number into standard form, count the number of spaces it takes to move the decimal point into a position where the resulting number is between 1 and 9. The number of spaces moved will be the ‘n’ value in your answer. A movement to the left means the ‘n’ value will be positive. A movement to the right means the ‘n’ value will be negative. Remember that any power raised to 0 is 1. Vertical Divider
