Question

Does anyone know this one? Thanks

Answer 1

`3.844\,*\,10^5`

So a=3.844 and b=5

Step-by-step 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:

`384,400=3.844 \,*\,100,000= 3.844 \,*\,10^5`

with a=3.844, and "5" as the exponent of ten (so b=5)
