The best way to gain confidence in mathematics is by studying solved examples. By analyzing how formulas are applied step-by-step, you learn how to tackle complex questions in your homework and exams. Let's walk through standard worked examples for Class 8 Algebraic Expressions and Identities.
Step-by-Step Solved Problems
Example 1: Applying Identities
Question: Find the value of 103² using algebraic identities.
Worked Solution Steps:
- Write 103 as (100 + 3).
- Apply identity (a+b)² = a² + 2ab + b².
- Substitute: 100² + 2*100*3 + 3².
- Evaluate: 10000 + 600 + 9 = 10609.
Final Answer: 10609
Self-Practice Method
