Provide an appropriate response.Paul notes that if a = 3 and b = -3, then 
= 
= -1. He concludes that for any real numbers a and b, 
= 
. Do you agree with his reasoning? If not, why not?
What will be an ideal response?
is not equal to 
for any a and b. In fact 
is equal to 
only if a = b or a = -b. Paul has stated that 
= 
for all real numbers a and b. To disprove this statement, it is sufficient to find one counterexample.
One possible counterexample is a = 2, b = 6. Then 
= 
, but 
= 3.
