Ok, so it's known that the Cartesian product of measurable sets is measurable, and the measure of the product is product of the measures (i.e. if A, B are measurable, then m(AxB)=m(A)m(B) for some given measure m, for example the Lebesque measure). Now, how can I show that:
a) the product of nonmeasurable sets is nonmeasurable (i assume, it's not)
b)the product of nonmeasurable set and a measurble set with non-zero measure is nonmeasurable
P.S.: any help will be appreciated:D
