Worked Example
Revision challenge 9
For Class 7 Mathematics, explain or solve a expressing large numbers in standard form question from the chapter "Exponents and Powers". Focus on revision challenge and show the working clearly.
Step-by-step solution path
- Read the topic idea: Expressing large numbers in standard form.
- Recall the core explanation from the chapter: Mathematics syllabus chapter for Class 7.
- Use the related formula "aᵐ × aⁿ = aᵐ⁺ⁿ" 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 Expressing large numbers in standard form. A strong solution should identify the correct data, apply aᵐ × aⁿ = aᵐ⁺ⁿ, and explain each transition instead of jumping directly to the answer.
