Step-by-step solution path
Read the topic idea: Types of Numbers.
Recall the core explanation from the chapter: Real numbers, irrational numbers, laws of exponents and their decimal expansions.
Use the related formula "nth Root" 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 Types of Numbers. A strong solution should identify the correct data, apply nth Root, and explain each transition instead of jumping directly to the answer.
