630 digits.
You would get 9 single digits. You would get one digit for 1 through 9 and the rest of the numbers would be more than one digit.
You would need infinitely many digits to write all numbers. However, to write all whole number (integers) you would need 4243.
744 digits.
We only use 10 digits (0 through 9), so I would say, there is one of them.
76
1000
how many different ways can you use the digits 3 and to write expressions in exponential form/ what are the expressions
If you use each number once, there are six combinations.
4 digits on each foot which would equal 8 digits in all 4 digits on each foot which would equal 8 digits in all
Almost got me on this one. 20 numbers but 29 digits
If the decimal is say .5489 Then write 5489 as the numerator and write the denominator as 1 (for the decimal point) followed by as many digits you have after the decimal point. So in this case the fraction would be 5489/10000
-99
