In order to find out what it should be the scientific notation, you've got to get it between 0.1 and 9.9, therefore, you've got to divide it by 10 million
46,500,000 / 10,000,000 = 4.65
This is then in the correct form, and you've then got to find the notation.
To do this, you need to keep dividing 10,000,000 until you get to 10.
10,000,000/10= 1,000,000/ 10= 100,000/ 10= 10,000/10= 1,000/ 10= 100/10= 10
You've divided it by ten six times, therefore, the scientific notation is 10^6.
Therefore, 46,500,000 in scientific notation is 4.65 x 10^6
Hope this helps :)
