First you would want to move a decimal place to the right one position(4,500, 4.500).
Then you are now going to want to count how many places to the right of the decimal ( there are 3 places to the right of the decimal).
So building upon what you know, you can now reconstruct the number into scientific notation. Now you are going to the decimal number 4.5 and times with 10 to the third power ( 10 ^3). Now to check your work to see if you did it correctly, you would do 10 to the third power equals 1,000 times 4.5 which equals 4,500 ( 10^3 = 1,000 x 4.5 = 4,500 or 4500.
