In how many ways can you arrange the numbers 2 4 6 and 8 to make a four-digit number?
24 (You said "arrange" rather than "use," so I assume you want to use each digit only once).There are 4 choices for the first digit. Once you choose it, you have 3 choices left for the second digit. Likewise, you have 2 choices for the third digit and only one choice for the 4th digit.Thus, you have 4 x 3 x 2 x 1 = 24 ways of making a 4 digit number with these digits.
In how many ways can you arrange the numbers 0 2 4 6 and 8 to make a four-digit number?
Assuming no repeats and possible can start with the zero: First digit can be one of 5, second digit can be one of 4 etc, so there a re 5 x 4 x 3 x 2 possibles ie 120
How many 4 digit numbers can you make out of this 4 digit number 1234?
24 = 4*3*2*1
How many digit numbers can be formed from the digit 2 3 5 7 8?
To determine how many digit numbers can be formed using the digits 2, 3, 5, 7, and 8, we need to consider the number of digits in the numbers we are forming. For a 1-digit number, we can use any of the 5 digits. For a 2-digit number, we can choose 2 out of the 5 digits and arrange them, giving us (5 \times 4) combinations. We can continue this for 3-digit, 4-digit, and 5-digit numbers, which will yield (5), (20), (60), and (120) respectively. Therefore, the total number of digit numbers is (5 + 20 + 60 + 120 = 205).

How many zeros does a thousand digit number have?
A Thousand digit number will have 999 zeros
How many 3-digit numbers are there using 2 4 6 8 and 9?
There are 5 numbers which can make the 3 digit numbers in this example. Therefore each digit in the 3 digit number has 5 choices of which number can be placed there. Therefore number of 3 digit numbers = 5 x 5 x 5 = 125

How many numbers make a palindrome?
A palindromic number can have as few as one digit, and as many as infinity. The smallest palindromic number is zero and the largest is '999... to infinity'.

Six of them.
How many times can you make a four digit number without repeating any?
