Two examples of applying exponents to fractions in certain ways. Other examples should be investigated.
|
|
|
A brief description of the difference between rational and irrational numbers followed by examples of number in both categories.
|
|
|
A brief description of what integers consist of followed by a list of numbers where it is decided whether each is an integer or not.

|
|
This discusses what rationals and irratioinals are, then goes on to demonstrate how to eliminate any radical number in the denominator.
|
|
|
This demonstrates creating a multiplication in the numerator of a rational expression that will allow the expression to be reduced by dividing like factors to simply one
|
|
|
Demonstrations that emphasize the fact that a fraction bar acts like parentheses in that the each part of the fraction must be factored so that there is a product of factors on both top and bottomof…

Shows how to manipulate fractional exponents in variou sways

|
|
Two examples of how to apply a fractional exponent to a whole number base.
|
|
|
This one demonstrates how to eliminate the rational parts of the equation as usual, then gather the terms with the chosen variable on one side of the equal sign so that it can be factored to one…
|
|
|
Demonstrates how to rearrange a proportion to isolate a chosen variable. Note that none of the variables are elliminated, simply moved to new positions.
|
|
|
Demonstrates using factoring skills to separate and identify all of the necessary factors that make the LCD (Least common denominator) that can be used as a multiplier through a rational equation to…
|
|
|
Shows how to find a common denominator to use as a multiplier for each term in a rational equation (an equation with fractions) to then eliminate the denotminators and the result will be a more…

|
|
This has two examples so that you can learn to watch out for what looks like a solution but is not because it creates division by zero if you check the answer in the original equation. The other…

|
This demonstrates how to convert negative exponents in a complex fraction to the reciprocal positive exponents and then use the LCD of all fractions to simplify.
|
|
|
Demonstrates multiplying each term in a rational equation by the least common denominator of all fractions so that the denominators can be eliminated and the resulting linear equation can then be…
|
|
|
Shows cross multipication of two single fractions set equat to each other to create a new equation that has no fractions and is then solvable by the typical methods.
