Suppose c = ab, where a, b, and c are integers and a and b are prime. How many positive integers less than or equal to c are neither evenly divisible by a nor evenly divisible by b? (Use the subtraction rule from the text). help please?
Yosh!!!... Are you still around?
well..I am ready to help you to find answer on your own.....ok...I think you will b abletofigure out from what I right.... if not ask
let us take an example... let 'a' =2 and 'b'=3 therefore the product will be \['ab' = 2 \times 3 = 6\] now how many times 2 can be evenly divisible by 3 = ? and how many times 3 can be evenly divisible by 2 = ? (if you relpy or try to provid answer to above questions I will write next steps...because...I don't like to write answer directly) ;)
