What is the value of ((4-2)!)?

Answer and explanation

Correct answer: 2

Evaluate the bracket first: \(4-2=2\). Thus, the expression becomes \(2!\). Since \(2!=2\times1=2\), the correct answer is 2. Directly taking the factorial of 4 would give \(4!=24\), which is not the given expression. Exam tip: always simplify the expression inside brackets before evaluating a factorial.
