Just a quick couple of examples, one explaining the relationship between squaring and square rooting and one that just shows how to multiply two radical expressions that need no reduction.


Discusses the square root property, then encourages the viewer to write a list of perfect squares in the marginfor reference. Lasly, three examples are presented and solved.


Two examples are shown here, one relatively easy, then one with some fractions involved.


This shows how to multiply by a form of one created by using the irrational denominaor to multiply by the top and the bottom of the fraction creating a whole number denominaor.


Shows that the division of sqaure roots is equivalent to the square root of a fraction, and then simplifies the fraction to complete the task.


Shows how to separate out the persct square so they can become whole numbers or expression leaving the remaining factors under the square root.


Thisi shows how to break down a square root by dividing out perfect squares that can become whole numbers.


Shows how square rooting is the opposite of squariing


Squaring both sides of this equation means squaring a binomial. This is demonstrated by this video.


This demonstrates how to solve an equation where two radicals are equal and there are no other terms on either side of th equation


This video shows how to multiplly the top and bottom of a square root of a fraction to get the result of a rational number in the denominator.


This describes what to look for when simplifying radicals.


Application of the equation relating the three sides of a right triangle:: a^2 + b^2 = c^2 where a and b are the shorter sides that make the rigiht angle and c is the lenght of the longest side.


A quick run through the use of a^2 + b^2 = c^2 to find an unknown side of a right tirangle if we know the other two sides.
