17.
Short Answer Simplify: (24 - 8) ÷ 4 Of 2 using BODMAS. Provide the detailed process.
2 pts
Answer: Step 1: Evaluate the bracket: 24 - 8 = 16 Step 2: Divide by 4: 16 ÷ 4 = 4 Step 3: Apply Of operation: 4 Of 2 = 4² = 16 Note: Alternatively, if the intended operation is to compute (24-8) first then Of 2, then 16 Of 2 = 256 and 256 ÷ 4 = 64. Clarification: Based on BODMAS, Of has higher precedence than division. Therefore, recalculate as: Step 1: 24 - 8 = 16 Step 2: Apply Of operation: 16 Of 2 = 16² = 256 Step 3: Divide: 256 ÷ 4 = 64 Final Answer: 64
