Two examples of distributing radicals into a sum of other radicals and simplifying in the process.
|
|
|
A quick distribution of a radical into the sum of two numerical terms, one whole and one radical as well.
|
|
|
In this example, the multiplication of two fourth-roots of numbers is shown and the reduction of the result
|
|
|
The combining of like factors from two radicals into one and then the simplification of the result.
|
|
|
A short demonstration of multiplying and then reducing the result when presented with the product of two radical expressions.
|
|
|
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.
|
|
|
Demonstrates how to solve for a variable under the radical that needs to isolated first after entering the given value for the other variable in a formula.
|
|
|
Describes how to approach solving a radical eqaution, then demonstrates the stepss needed. It finishes with a check of the answers, stressing that this is an essential step.
|
|
|
Shows how to substitite the given value for the output variable, then rearranges the resulting equation in standard form. Values for a, b, and c are identified and then entered into the quadratic…
|
|
|
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.
|
|
|
This includesradicals that contain variable factors, but continues the simplification of various terms in a sum or difference so that possible like terms can be added orsubtracted.
|
|
|
This shows how to simplify the parts of an addition of radicals and then add or subtract the like terms.
|
|
|
This shows how to simplify square roots in an additon problem so that hopefully you get like terms and con simplify further.
