i need help with a proof regarding intersection of family ofsets, but dont know how to post it with the symbol of upside down Uand i = 1 on bottom and n on top... so if we can use "U" torepresent the Upside down u with i = 1 on bottom and n on top, hereis the help I need... If A1, A2... and B are any sets then for anypositive integer n, "U" (Ai x B) = ("U"Ai) x B.. if there is abetter way to post this please let me know

Discrete Math Prove: If A1, A2... and B are any sets then for any positive integer n, n (Aix B) = (A) X B x i=1 i=1
