Square Root

Square Roots The square root of a number is the number you can multiply by itself to give you that numbers Square of a = a2 = a x a Square of a number is a raised to the power 2 Square root of a = √a where √ means square root Square root of a number a is a raised to the power of √a = a

√4 = √22=(22) 2 4 (2 x 2 =22) =2 14 √196 = √142 =(142) 196 (14 x 14 =142) =14 25 √625 = √252=(252) 625 (25 x 25 =252) =25 99 √9801 = √992=(992) 9801 (99 x 99 =992) =99

Try these Find the value of square root √9 , √81 , √196 , √256 , √361
