is a real number. Is positive, negative, or zero?
Statement 1:
Statement 2:
BOTH statements TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient to answer the question.
Statement 2 ALONE is sufficient to answer the question, but Statement 1 ALONE is NOT sufficient to answer the question.
BOTH statements TOGETHER are insufficient to answer the question.
EITHER statement ALONE is sufficient to answer the question.
Statement 1 ALONE is sufficient to answer the question, but Statement 2 ALONE is NOT sufficient to answer the question.
Simplify this expression as much as possible:
\sqrt[3]{16} + \sqrt[3]{128} - \sqrt[3]{54}
9 \sqrt[3]{2}
4 + 4\sqrt[3]{2} - 3 \sqrt[3]{6}
The expression is already simplified
3 \sqrt[3]{2}
\sqrt[3]{198}
is a real number. Is 
positive, negative, or zero?
