What is the difference between the greatest and the smallest four-digit number that each formed by different digits?
given that m=999...99;2001 digits and n=888...88; 2001 digits, find the sum of the digits in the value of m*n
giúp với,mik cần gấp,viết lời giải!
The sum of the digits of m is 9*2001=18009
The sum of the digits of n is 8*2001= 16008
We have 1+8+0+0+9=18
1+6+0+0+8=15
18*15= 270
=> the sum of the digits in the value of m*n is 2+7+0 =9
