Step-by-step explanation:
The scientific notation of any number is given by :
[tex]N=a\times 10^b[/tex]
a is any real no and b is any integer
The scientific notation of 345,000,000 should be [tex]3.45\times 10^8[/tex] but Jorden wrote 34.5×10⁷. He is incorrect. He should have shifted decimal before 4 such that power of 10 becomes 8.
