Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, the way you wrote the number is the standard form for your example.
800
Assuming those were added, the standard form is: 2,070,173,810
Each of those numbers already is in standard form.
372,512,805
well, actually 800 is incorrect its actually in thousands. Think of it this way, 80 is equivalent to 8 tens right? How abt 80 tens? Nope! Not 80! It's 800. Now 800 tens is 8000. So 893 hundreds is a bit tricky. 893 tens would be 8,930. In hundreds your answer would be 89,300. Yup! Ten thousands! Whoever said 800 was the answer is stupid as hell.
The standard form is $3,000,800.00
9+800 is how you write it in standard form
800
20,805 is standard form 20,000 + 800 + 5 is expanded form 2.1 * 104 is scientific form
The standard form is: 200,000,000,010,000,070,000,300,080,010
