There might be more than one answer but I came up with this;
8x8x8= 512
8x8x8= 512
8+8+8=24
So if you add the first two numbers (512 twice) that makes 1024.
Then you simply minus the last number which is 24 and it equals 1000.
The total number of 8's also equal 9.
Enjoy :]

Unfortunately the first answer I gave used 9 8's whilst you were only allowed 8 of the chosen digit.
Here's my second attempt;
If you add two 5's together it equals 10
Do this two more times.
So you have three 10's.
Now simply times these together.
So that's: (5+5)(5+5)(5+5)= 1000
There you go finally and I only used the digits 6 times! ;D

Hi,
And the correct answer is
(8*8+8*8)*8-(8+8+8)
Here one digit is used exactly eight times
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
10 x 9 x 8 = 720.
You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.

1,000,000. Specifically, they are all numbers from 000000-999999
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
You have seven different digits (symbols) to choose from, so you can form seven different one digit numbers and 7×7=72=49 different two digit numbers.
8 of them.
888, 88, 8, 8, 8.
There are 27 of them.
Number of 7 digit combinations out of the 10 one-digit numbers = 120.
10 x 9 x 8 = 720.
There are 4 items to choose from, and 3 of them, so the answer is 43 = 64.
You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.
a lot
