Standard Form (6.8 x 10^12)
Standard form is a way of representing a very large or very small number. It is based on using powers of 10 to express how big or small a number is.
It is written in the form:
Where 'a' is a number between 1 and 10 and n is a positive or negative integer number
Standard form is often used by scientists to show the mass of planets or the distance of galaxies, where the numbers are extremely large or even to show the size of a bacterial cell or atom, where the numbers are extremely small.
