Let's write 48,020,000 expressed in scientific notation:
Let's recall that scientific notation is the method used by scientists to easily handle either very large numbers or very small numbers.
The scientific notation is formed by two numbers: the digit term and the exponential term.
The digit term is always a number between 1 and 10 and the exponential term is the number of places the decimal point must be shifted to give the number in long form, either positive or negative when numbers are lower than 1.
Upon saying that, in our exercise we have:
4.802 (Digit term that should be between 1 and 10, as we explained above)
10^7 (Exponential term that moves the decimal point to the right)
The scientific notation then is:
4.802 * 10^7 = 48,020,000
4.802 * 10,000,000 = 48,020,000
The correct answer is:
A. 4.802 x 10^7
