What is the value of (31^3)?
Answer and explanation
Correct answer: 29791
An exponent of 3 means multiplying 31 by itself three times: \(31^3=31\times31\times31\). First, \(31\times31=961\), and then \(961\times31=29791\). Therefore, 29791 is correct. A value such as 30791 can result from a small multiplication error. In exams, find the square first and then multiply by the same number.
