Study Notes
Square Numbers
- A square number is the result of a number multiplied by itself.
- Example: 3 * 3 = 9, where 9 is a square number.
- Another notation for squares is using a superscript "2": 3² = 9.
- Square numbers are used to calculate the area of squares.
- The area of a square is calculated by multiplying the side length by itself: Area = side * side = a * a = a².
- If the side length of a square is 3 meters, the area is 3m * 3m = 9m².
Square Roots
- Finding the square root is the reverse operation of squaring a number.
- The square root of a number n is represented as √n.
- The square root of a number is the number that, when multiplied by itself, gives the original number.
- Example: √(8m²) = √((3m)²) = √(3m * 3m) = 3m.
- √(3)² = 3, √(9) = 3.
