Square roots of perfect squares

The  exercise appears under the 8th Grade Math Mission. This exercise is an arithmetic drill for positive square roots of perfect squares.

Types of Problems
There is one type of problem in this exercise:


 * 1) Find the square root of the number: This problem asks for the square root of a given number. The student is expected to find the square root and write it in the space provided.Srops1.png

Strategies
Knowledge of the 12 by 12 times tables is sufficient to do this exercise correctly. Practice will increase speed if needed.
 * 1) All the numbers under the radicals will be perfect squares, therefore the answers will all be integers.
 * 2) The largest number seen so far is the square root of 144.

Real-life applications

 * 1) Square roots have many uses in the physics as they are the way to undo squares in famous formulas like E=mc^2.
 * 2) Applications to trigonometry are also evident since the right triangle trigonometry is based on the Pythagorean Theorem.
 * 3) In geometry, the square root is necessary to find the distance between points or the magnitude of a vector.
