Perfect Square & Square Root
- A perfect square is a number that results when a whole number is multiplied by itself.
- Examples include 4 (2 x 2), 9 (3 x 3), 16 (4 x 4), and 25 (5 x 5).
- A square can be formed using the number of unit squares that make up the perfect square; 4 unit squares can form a perfect square.
Identifying Perfect Squares
- A perfect square is a number that has an integer square root.
- Methods to determine perfect squares are: -Trial and error -Prime factorization -Using a calculator -Familiarization with a list of perfect squares
Square Root
- The square root of a number is the value that, when multiplied by itself,gives the original number.
- Examples: √16 = 4 (because 4 x 4 = 16) and √25 = 5 (because 5 x 5 = 25).
- The symbol √ is called the radical sign; the number under the radical sign is called the radicand.
- The square root of a number m is expressed as √m.
Application Example
- Ms. Santos has a square garden with an area of 64 square meters.
- To find the fencing needed, determine the side length of the square garden (√64 = 8 meters).
- Then calculate the perimeter (4 x side = 4 x 8 = 32 meters).
- Ms. Santos will need 32 meters of fencing.
