Answer:
In which number does 8 have a greater value, 81, 734, or 8,999?
The number 8 by itself is always equal to 8 or to 8 ones = 8×1.
In the denary (base 10 ) number system
81=8×101+1×100
=8×10+1,
so that the digit 8 represents 8 tens or 80.
There is no 8 in the denary number 734.
8,999=8×103+9×102+9×101+9×100
=8×1000+9×100+9×10+9×1
so that the digit 8 represents 8,000.
Considering its positions in the three numbers given, the digit 8 represents the greatest value in the number 8,999.
