[im indicating a subscript by parenthesis... as in a sub 1 = a(1) not multiplying]
By PMI, prove that this statement is true:
"If p is a prime number and p | a(1)*a(2)...a(n), where a(i) is an integer for i=1,2,3...n then p | a(i) for some integer i.
(im especially confused at what the make my proposition P(k) and where to substitute the k for PMI.)
thank you so much
