Exercise 12 Page 491

What are the common factors in the product of the three even integers?

See solution

Practice makes perfect

An inductive reasoning uses specific examples to find patterns in order to form a conjecture. Let's calculate the product of three even numbers and see what happens: First trial:& 2*4*6 =48 Second trial:& 4* 6* 8 =192 Third trial:& 6* 8* 10 =480 It's not very easy to discern a pattern, but each of these products is even. Now let's use deductive reasoning to prove the conjecture: the product of three even integers is even. Let 2x, 2y, and 2z represent any three even integers.

2x(2y)(2z)
8xyz
2(4xyz)

Since (4xyz) is being multiplied by 2, the number 2(4xyz) is an even number. VOILA!!
