Answer:
4.83 * 10^9
Explanation:
Here, we want to express the given number in scientific notation 
What we have to do here is to place the decimal number at the back of the first non zero number 
The first non zero number is 4 
So
let us count the number of digits after the first non zero number 
That will be 9
So we make this the power of 10 
And our answer will be;
4.83 *10^9
