What is the value of (27^3)?
Answer and explanation
Correct answer: 19683
The exponent 3 means that 27 is multiplied by itself three times: \(27^3=27\times27\times27\). First, \(27\times27=729\), and then \(729\times27=19683\). Therefore, 19683 is correct. A value such as 18683 can result from an arithmetic error during multiplication. In exams, write a power as repeated multiplication to check the calculation.
