Answer 2

Step-by-step explanation:

Thus 1+1+1+1+2+1+1+1+1 = 10 . Thus the power will be 10 which can divide 90 x 80 x 70 x 60 x 50 x 40 x 30 x 20 x 10. It is evident that there are 10 5s involved in the multiplication. Hence, 10 is the highest power of 5 which shall divide the given multiplication.
