Answer and explanation
Correct answer: 256
\(2^8\) means multiplying 2 by itself eight times: \(2\times2\times2\times2\times2\times2\times2\times2=256\). Therefore, 256 is correct. Note that 128 is the value of \(2^7\), not \(2^8\). Exam tip: Remember consecutive powers of 2: \(2^6=64\), \(2^7=128\), and \(2^8=256\).
