What is the value of 38^3?
Answer and explanation
Correct answer: 54872
Compute stepwise: first square 38: \(38\times38=1444\). Then multiply by 38: \(1444\times38=1444\times(30+8)=43320+11552=54872\). So 54872 is correct. Option C (55872) is wrong because it differs by 1000 — a typical arithmetic slip (adding/subtracting a power of ten). Exam tip: for cubes, calculate the square first and then multiply by the base to reduce mistakes.
