What is the value of (19^3)?
Answer and explanation
Correct answer: 6859
An exponent of 3 means multiplying 19 by itself three times: \(19^3=19\times19\times19\). First, \(19\times19=361\), and then \(361\times19=6859\). Therefore, 6859 is correct. A value such as 6759 can result from an arithmetic error in multiplication. Exam tip: to find a cube, first square the number and then multiply by the same number.
