What is the value of (13^3)?
Answer and explanation
Correct answer: 2197
An exponent of 3 means multiplying 13 by itself three times: \(13^3=13\times13\times13\). First, \(13\times13=169\), and then \(169\times13=2197\). Therefore, the correct answer is 2197. The value 169 is \(13^2\), so it is a close but incorrect option. Exam tip: Rewrite \(a^3\) as \(a\times a\times a\) before calculating.
