The smelliness of cheese (denoted by sss) can be defined as a function of the amount of bacteria in the cheese (denoted by bbb) and the surface area of the cheese (denoted by aaa) using this formula: s = { b\cdot a}s=b⋅as, equals, b, dot, a surface area of the cheese is measured in \text{cm}^2cm 2 c, m, start superscript, 2, end superscript. select an appropriate measurement unit for smelliness of cheese.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
