Question

Prove that the product of r consecutive positive integers is divisible by r!

​

Answer 1

Answer:

ok dear see below

Step-by-step explanation:

It is because of the negative integers to the positive ! let's see how if we multiply 2 × 2 then it will become four and if we divide 2 multiply 9 then it will become 18 so can we divide 4 by 18 ? obviously no ! because 19 ÷ 4 is equal to 4.75 but if we will divide 16 / 4 then it will come 4 ! understand what I am saying ?

Okay thanks !
