Exponents, Square Root and Scientific Notation: Student develops the concept behind the power of a number. It begins by learning the square and cube geometric meanings and their roots. Students will figure out in between what whole numbers is a given root. The concept is extended to learn about powers of 10, and scientific notation.
Interactive Applets: Relevant Theorems.
A perfect square may be geometrically represented by a square, for which the side
is the square root of the squared number. Try to manipulate the below applet to visualize this
representation of a squared number, and its root.
One question we often do is: In between what two whole numbers is the square root of a
given number? In this applet you will be able to view it by forming a red square with equal
NON-INTEGER SIDE LENGTHS, and fitting this IN BETWEEN a large blue square, and a small green
square with INTEGER SIDE LENGTHS. Read carefully the directions in the applet.
