9th Class Math Review Exercise| Exam Preparation | Tez Tairi Series Day5 Verifying Algebraic Equations (0:00-11:20): The video begins by demonstrating how to verify algebraic identities. Left Hand Side (LHS) and Right Hand Side (RHS) verification (0:35-6:10): The instructor shows how to solve both sides of an equation to prove their equality. Second verification example (6:13-11:20): Another similar problem is solved to reinforce the concept. Understanding Rational Numbers (11:20-12:50): The video clarifies the definition of a rational number. Is zero a rational number? (11:31): The instructor explains why zero is considered a rational number, providing examples. Finding Rational Numbers Between Two Integers (12:54-15:38): The video demonstrates how to find rational numbers between two given integers. Finding the first rational number (13:05-13:39): A method for calculating the first rational number is shown. Finding the second rational number (13:42-15:15): The process for finding a second rational number is explained. Simplifying Expressions (15:40-20:38): The video provides instructions on simplifying expressions involving roots and exponents. Simplifying expressions with fractional exponents (15:40-16:50): An example of simplifying an expression with a root that can be written as a fractional exponent is demonstrated. Simplifying expressions with cube roots (16:53-18:18): Another example focusing on cube roots and exponents is shown. Simplifying complex exponential expressions (18:20-20:38): The video concludes with a more complex simplification problem involving multiple exponential terms.
