Ironically, the phrase "standard form" is not standard!
In the UK, standard form is generally taken to refer to the scientific form. In that case, there are nine numbers: 1 to 9.
The answer is 20 and they are: 1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,8… and 200 The reason is the expanded form of lets say 11 is 10+1 in which case it is not identical to its standard form. Numbers such as 30 is only 30 and is identical to its standard form.
1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90,100,200
10 , what are they?
0123456789,10,20 30 40 50 60 70 80 90 100 200
Because the basis for expansion are the powers of ten - exactly the same as in the standard form.
0,1,2,3,4,5,6,7,8,9. also any single digit followed up with all 0's for example - 100, 3000, 90. a number like 110 would not qualify
In standard form it is 1*10^-1.In expanded form it is 0.1
Expanded form: 700 + 70 + 9 + 0.3 + 0.06 Standard form: 7.7936*102
8.12 in standard form. 8+0.1+0.02 in expanded
In standard form it is 1.1*10^-2.In expanded form it is 0.01 + 0.001
arabic numbers or decimal numbers
Because it may have a deciml in it
