3 × 9
5 × 7

Hint:
a number N is said to be even if there exist a another number K , for which N = 2 x K second definition : when a even number is divided by 2 , we will not get any reminder
The correct answer is: 9 × 8
9 x 8 is the correct answer Step 1: 3 × 9 = 27 5 × 7 = 35 5 × 3 = 15 Step 2: Only 9 × 8 = 72 is even. because when we divide 72 by 2 we will not get any reminder, so 72 is a even number
