Okay, let's take this one step at a time. According to the Order of Operations Theorem, you must find all the products before you add all the terms together.
[tex]2 (10,000)=20,000[/tex]
[tex]7 (1,000)=7,000[/tex]
[tex]4 (100)=400[/tex]
[tex]9(1)=9[/tex]
[tex] 3 (1/10)=0.3[/tex]
[tex] 8(1/1,000)=0.008[/tex]
Now, let's add those numbers together.
[tex]20,000+7,000+400+9+0.3+0.008=27,409.308[/tex]
Answer: [tex]27,409.308[/tex]
hope this helps!
