Question
Which numbers are not counterexamples for the following statement?
For any numbers a and b, 
= a - b
- a = 8, b = 4
- a = 10, b = 5
- a = 6, b = 3
- a = 4, b = 2
Hint:
step 1 - Let a = 4, b=2
step 2 - = 4/2 = 2
step 3 - a - b = 4-2 = 2
The correct answer is: a = 4, b = 2
Given statement, = a - b
Therefore, a = 4, b = 2 satisfies the statement = a - b. Hence, a = 4, b = 2 are not counterexamples of the statement = a - b.
