Answer and explanation
Correct answer: 200
Here, 6^3 = 6 × 6 × 6 = 216 and 2^4 = 2 × 2 × 2 × 2 = 16. Therefore, 6^3 - 2^4 = 216 - 16 = 200, so option B is correct. A value such as 210 can result from evaluating 2^4 incorrectly. Exam tip: calculate each power separately before performing subtraction.
