What is the value of (20^3)?
Answer and explanation
Correct answer: 8000
An exponent of 3 means multiplying 20 by itself three times: \(20^3 = 20 \times 20 \times 20 = 400 \times 20 = 8000\). Therefore, 8000 is the correct answer. The value 4000 would be \(20 \times 20 \times 10\), so it is not correct. Exam tip: To find a cube, multiply the number by itself three times.
