Adding and Subtracting Radicals

• Radicals that have the same index and the same radicand are called like radicals.

• You can apply the distributive property to add/ subtract like radicals in the same way as like terms.

Combine like terms/ like radicals

•Like terms:• 5x+y-4x=

•Like radicals:

* First simplify each radical, then combine them if possible.

Summary

•Write the rules that you know and use effectively.

•Support this rule with an example.•What you have learned up to this stage.

•What you have not learned or which parts of the subject is unclear to you.

Mixed Examples (Simplify)• * Assume that each radical represents a real number.

Rule 10:

Arrow Paradox of Zeno• In the arrow paradox, Zeno states that for motion to occur,

an object must change the position which it occupies.• He gives an example of an arrow in flight. He states that in

any one (durationless) instant of time, the arrow is neither moving to where it is, nor to where it is not. It cannot move to where it is not, because no time elapses for it to move there; it cannot move to where it is, because it is already there.

• In other words, at every instant of time there is no motion occurring. If everything is motionless at every instant, and time is entirely composed of instants, then motion is impossible.
