Which expression is INCORRECT?
A√4 = 2
B|−7| = 7
C0/5 = 0
D5/0 = 0
Answer & Solution
Correct answer: D. 5/0 = 0
5/0 is UNDEFINED, not 0. Dividing by zero has no defined result. (0/5 = 0 is fine — zero divided by 5 is zero.) Many students confuse these: zero in numerator gives 0; zero in denominator gives undefined.
