What is the value of (2^9)?
Answer and explanation
Correct answer: 512
An exponent of 9 means multiplying 2 by itself nine times: \(2^9=2\times2\times2\times2\times2\times2\times2\times2\times2=512\). Therefore, 512 is correct. The close distractor 256 equals \(2^8\), not \(2^9\). Exam tip: Remember consecutive powers of 2; doubling \(2^8=256\) gives \(2^9=512\).
