interesting puzzle to find three more of them--the smallest possible
numbers. What are they?

the cube of 2 (8), the product of which is 5,000. But he printed 5^4×2^3

manner shown, so that it will be equally correct if the printer sets it

He found that if he gave away the same number of pounds every day in the
