Which of the following expressions is equal to \(2^5\)?
Answer and explanation
Correct answer: \(2 \times 2 \times 2 \times 2 \times 2\)
\(2^5\) means multiplying 2 by itself five times: \(2 \times 2 \times 2 \times 2 \times 2\). Therefore, option B is correct. Option D represents adding 2 five times, which equals \(2 \times 5\), not \(2^5\). Exam tip: In \(a^n\), \(a\) is the base and \(n\) tells how many times the base is used as a factor.
