If (x^3=2744) then what is (x)?
Advertisement
Answer and explanation
Correct answer: 14
Since \(14^3=14×14×14=2744\), it follows that \(x^3=2744\) gives \(x=\sqrt[3]{2744}=14\). The cubes of the other options are not equal to 2744. Exam tip: identify the nearest perfect cube first; here, \(14^3=2744\).
