You will estimate the square roots of non-perfect squares by determining the square roots of the nearest perfect squares (in order to find the appropriate frames for paintings in an art exhibit).
After completing this tutorial, you will be able to complete the following:
A number p is called a perfect square if and only if there exists a whole number n for which
p = n2.
Take the whole numbers and square them:
02 = 0
12 = 1
22 = 4
32 = 9
and so on.
The resulting numbers 0, 1, 4, 9, 16, 25, 36 ... are called perfect squares.
Perfect squares can be represented pictorially by:
