The product of all positive integers less than or equal to 10 is written as 10! and is called "10 factorial". if 80! is written an a numeral, it will end with a long strip of zeroes. how many zeroes are in this string?
plz

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

What is the difference between the equations of a vertical and a horizontal line?
