Worked Example
Board-style short answer 5
For Class 8 Mathematics, explain or solve a powers with negative exponents question from the chapter "Exponents and Powers". Focus on board-style short answer and show the working clearly.
Step-by-step solution path
- Read the topic idea: Powers with negative exponents.
- Recall the core explanation from the chapter: Mathematics syllabus chapter for Class 8.
- Use the related formula "a⁻ⁿ = 1/aⁿ" as the main tool while solving.
- Write the reasoning in simple school-level language before the final answer.
Final learning answer
This example is centred on Powers with negative exponents. A strong solution should identify the correct data, apply a⁻ⁿ = 1/aⁿ, and explain each transition instead of jumping directly to the answer.
