If a × a = a², then a² is the square of a. Examples: 3 2 = 9 3 2 =9, 5 2 = 25 5 2 =25, ( − 4 ) 2 = 16 (−4) 2 =16 ✅ Properties of Square Numbers: A square number always ends with 0, 1, 4, 5, 6, or 9. Square of an odd number is always odd. Square of an even number is always even. Number of zeros at the end of a square number is always even. ➗ Square Root (√): Square root is the number that, when multiplied by itself, gives the original number. Example: 49 = 7 49 ​ =7 because 7 × 7 = 49 7×7=49 ✅ Perfect Square: A number whose square root is a whole number. Examples: 1, 4, 9, 16, 25, 36, 49, etc. ✅ Finding Square Roots: By Prime Factorization (for perfect squares) By Division Method (for large or decimal numbers) By Estimation (for non-perfect squares) 💡 Important Points: Every positive number has two square roots: one positive and one negative. 25 = ± 5 25 ​ =±5 Square root of a negative number is not real. #YASHCLASSESBYSURENDERSEHRAWAT, #SquaresAndSquareRoots, #Class8Math, #CBSEMaths, #NCERTMath, #PerfectSquares, #SquareRootTricks, #MathsIsFun, #MathRevision, #StudyWithMe, #MathConcepts, #LearnSquareRoots, #MathHelp, #EasyMathTricks, #MathematicsClass8, #Class8CBSE, #MathsForEveryone, #StudentLife, #StudySmart, #SquareNumbers, #MathsMadeSimple,
