Answer:
7
Explanation:
The significant figures are: 1,0,0,0,0,2,1
Remember the rules is
1. Non-digits are always significant.
2. Any zeros between two significant digits are significant.
3. A final zero or trailing zeros in the decimal portion only are significant
Those are three rules you have to follow in order to see how many significant figures there are in 10,000,210.
So I’m guessing 7 is the answer
Therefore the answer is 7.
