What is the value of (42^3)?
Answer and explanation
Correct answer: 74088
An exponent of 3 means multiplying 42 by itself three times: \(42^3 = 42 \times 42 \times 42\). First, \(42 \times 42 = 1764\), and then \(1764 \times 42 = 74088\). Therefore, the correct answer is 74088. A value such as 73088 can result from an arithmetic error in multiplication. Exam tip: to find a cube, first find the square of the number and then multiply it by the same number.
