If you allow leading zeros, then 4*4*4 = 64
If you don't allow leading zeros, then 3*4*4 = 48 (the numbers from decimal 16 to 63)
In base ten, there are 9000 four digit number, the numbers are from 1000 to 9999. If you allow leading zeros, then there are 10000 numbers. [0000 - 9999]
With 4 different numbers, 24.
10 * * * * * That is just plain wrong! It depends on how many numbers in each combination but there are 1 combination of 4 numbers out of 4, 4 combinations of 3 numbers out of 4, 6 combinations of 2 numbers out of 4, 4 combinations of 1 number out of 4. A grand total of 15 (= 24-1) combinations.
12 numbers
4,536 whole numbers or mixed numbers. 5,040 pure decimals.
The first digit has 4 choices for its digit. The second digit has 6 choices and the third has 3. The solution would simply be 4*6*3=72 three digit numbers.

There are infinitely many numbers in each system, however base 10 uses 10 digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} and binary uses 2 digits {0, 1}. The maximum digit is one less than the base.
In base ten, there are 9000 four digit number, the numbers are from 1000 to 9999. If you allow leading zeros, then there are 10000 numbers. [0000 - 9999]
The digit 6 has no meaning in base 4.
In the base-10 system, the 4-digit whole numbers are every number from 1,000 to 9,999. That's 9,000 numbers. If decimals are included, there are a lot more. For example, from .0001 to .9999 alone, there are over 9,000 more.
there are 4 numbers
take 20 blocks group them into sets of 4. How many sets did you make? 20 / 4 = 5
There are infinitely many numbers between 34 and 50 and so infinitely many sets of 4 numbers.
With 4 different numbers, 24.
base 4 would use the digits 0,1,2,3 so the first place digit would be 1,2,3 the 2nd place would be 0,1,2,3 and the 3rd place would be 0,1,2,3 3x4x4 =48
In a base ( A ) numbering system, the total number of 4-digit numbers can be calculated by considering that the first digit (most significant) cannot be zero. Therefore, for the first digit, there are ( A - 1 ) options (from 1 to ( A - 1 )), and for each of the remaining three digits, there are ( A ) options (from 0 to ( A - 1 )). Thus, the total number of 4-digit numbers in base ( A ) is given by the formula: ((A - 1) \times A^3).
