Lesson 66 Simplification of Radical Expressions, Square Roots of Large Numbers

Follow the same steps you did the night before. Read and listen carefully!

This video covers the topics in lesson 65 concerning Addition of Radical Expressions.


READ THE POST ON HOW TO WATCH A VIDEO FOR HOMEWORK BEFORE YOU START WATCHING THE VIDEO!


It would be best to watch the video full screen!  Do the problems that the teacher suggests you do. Pause the video and work them out. You can even read along with her in your text - she is using the same book.  YES!!

1.  Always have a writing utensil and paper when watching videos.

2.  Take notes on the video (remember you can pause and rewind).

3.  Workout example problems in the video on your own (with the video paused) or workout example problems that are given to you by the teacher.

4.  Write out any questions about the video that you would like to ask during class.

5.  If there is a mathematical error in the video write down the time it takes place in the video and an explanation of the error.

Note:  Create vocabulary list of math words that are specific to this lesson or new to you.  Create index cards to help you become more familiar with these terms.

Lesson 60 Vocabulary

Geometric Solid	A Geometric solid where two faces (called bases) are identical and parallel polygons and where the other faces are parallelograms (Lateral Faces)
Lateral Edges	Segments in which the lateral faces intersect into
Altitude	A perpendicular segment joining the planes of the bases
Height	The length of the Altitude
Right Prism	A prism whose lateral edges are at right angles to the bases
Right Triangular Prism	The bases are triangles
Right Rectangular Prism	The bases are rectangles
Right Trapezoidal Prism	The bases are trapezoids
Right Pentagonal Prism	The bases are pentagons
Cylinder	Is like a prism except the bases are closed curves instead of polygons
Lateral Surface	The curved surface between the bases
Right Circular Cylinder	Cylinder where the bases are circles
Right Cylinder	A cylinder whose axis is at right angles to the bases

Subset                          A set that is part of a larger set.

Proper Set                     A proper subset of a set, denoted, is a subset that is strictly contained in and so necessarily excludes at least one member of. The empty set is therefore a proper subset of any nonempty set.

Equal Sets                     Sets that have exactly the same members. (Two words, plural)

Improper Subset              A subset that includes the entire parent set; see proper subset.

Empty Set                     In mathematics, and more specifically set theory, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is. Some axiomatic set theories assure that the empty set exists by including an axiom of empty set; in other theories, its existence can be deduced. Many possible properties of sets are trivially true for the empty set.

Null Set                        A set that is empty; a set with no members.

Real Number                  Any rational or irrational number.

Infinite Set                    In set theory, an infinite set is a set that is not a finite set. Infinite sets may be countable or uncountable.

Natural Numbers             The number 1 and any other number obtained by adding 1 to it repeatedly.

Whole Numbers               A number without fractions; an integer.

Integers                        1. A whole number; a number that is not a fraction. 2. A thing complete in itself.

Rational Numbers              An integer or a fraction.

Irrational Numbers           A real number that cannot be expressed as a rational number.

Mutually Exclusive       Contradictory: unable to be both true at the same time.
