There are exclusions that make the expression 8ab^2/4a^2b-8ab^2 undefined. True or False.

Answer: True, there are values that would make the expression undefined.

When the denominator of an expression is equal to 0, then the expression is undefined.

In the case of a denominator of 4a^2b - 8ab^2, if either a or b is 0, then the denominator would be zero. And the expression would be undefined.
