What is the value of (40^3)?
Answer and explanation
Correct answer: 64000
Here, \(40^3=40\times40\times40\). First, \(40\times40=1600\), and then \(1600\times40=64000\). Therefore, the correct answer is 64000. The value 1600 is only \(40^2\), so it is a close but incorrect option. Exam tip: An exponent of 3 means multiplying the number by itself three times.
