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.
