Thank you for posting your math problem here. To convert 3.9x10^5mg to dg the answer is 3.9 x 10^3 dg. Below is the solution: 

Solution:

1mg=0.01dg 
 dg= 3.9 X 10^5mg
dg = (3.9 X 10^5) x 0.01
dg = 3.9 x 10^3 

Answer:

3900 dg

Explanation:

We know that 1 dg equals 100 mg

Now if we have [tex]3.9. 10^5 mg[/tex] to how many dg is equivalent

[tex]100 mg \longrightarrow 1dg\\3.9.10^5mg \longrightarrow x\\x=\frac{(3.9.10^5)(1)}{100}\\ x= 3900[/tex]

So [tex]3.9. 10^5 mg[/tex] equals 3900 dg
