Question

For two integers a and b , the products ab is even if at least one of the integers, a or b, even.

Could tell me the answer please

Answer 1

Hello from MrBillDoesMath!

Answer:

Suppose "a" is even. Then "a" is a multiple of the number 2, say a = 2k (where k is an integer), Then the product

ab = (2k)b = 2(kb)

is also a multiple of 2 and therefore even. In other words, the statement in the Question is true.

Thank you,

MrB
