Answer:
[tex]3.844\,*\,10^5[/tex]
So a=3.844 and b=5
Explanation:
Scientific notation requests to write a number using powers of ten as a factor accompanying a real number (a) between 1 and smaller than 10 that contains the digits to exactly represent the original number. So in this case, the number 384,400 can be written as:
[tex]384,400=3.844 \,*\,100,000= 3.844 \,*\,10^5[/tex]
with a=3.844, and "5" as the exponent of ten (so b=5)
