To square a number, just multiply it by itself. for eg. square of 3 is 3×3=9 "Squared" is often written as a 2 superscripted.
0 Squared=02=0 × 0=0 1 Squared=12=1 × 1=1 2 Squared=22=2 × 2=4 3 Squared=32=3 × 3=9 4 Squared=42=4 × 4=16 5 Squared=52=5 × 5=25 6 Squared=62=6 × 6=36 When we square a negative number we get a positive result. Square Roots
square root goes the other way 3 squared is 9, so a square root of 9 is 3 A square root of a number is a value that can be multiplied by itself to give the original number. A square root of 9 is 3, because when 3 is multiplied by itself we get 9.
square root of 9 could be −3 or +3 Because 9=3×3 $ 9=(-3)×(-3) symbol of square root is √
