Answer :
We can find the scientific notarion of this number by, as first step, identifying the base.
In this case, it is 5.2.
Then, we divide the original number by the base:
[tex]\frac{520,000,000}{5.2}=100,000,000[/tex]Then, we find the equivalent of this result in exponents of 10.
As we have 8 zeros after the one, we can write the following equality:
[tex]100,000,000=10^8[/tex]Then, we can write the number as:
[tex]520,000,000=5.2\cdot10^8[/tex]The scientific notation for this number is 5.2*10^8.
