4x + 3x = 7x
5x + 4y = 5x + 4y
Have like terms
Step 1 : simplify each term
Step 2 : combine like terms

Adding and subtracting radical expressions works like adding and subtracting expressions involving variables. Just as we need like terms when combining expressions involving variables we need like radicals in order to combine radical expressions.
4x + 3x = 7x
5x + 4y = 5x + 4y
Have like terms

I am putting in some links for reviewing material.
roots and radicals (videos)
rational exponents (tutorial with practice questions)
simplifying radical expressions (m/c quiz)
operations with radicals (m/c quiz)
Hope this helps and have fun!!! Ms Armstrong

Radicals
1. Break up what's under the square root sign into a product of factors, finding the LARGEST PERFECT SQUARE.
2. Split up and simplify.
Examples :
1. Factors of 20 : 1, 2, 4, 5, 10, 20. In this case, 4 is the perfect square.
Definition : A radical is any expression under a square root sign.
* Our goal is to be able to simplify radicals to their simplest form.

4. Seeing how it's the square root of 3. You are going to have to find a number multiplied by itself 3 times instead of 2.
Factors of 40 : 1, 2, 4, 5, 8, 10, 20, 40. (Perfect cube = 2 x 2 x 2 = 8)
5.
After the teacher gave some examples, he instructed us to do exercise 33. You have to omit questions 5, 12, and lastly 7. The next blogger is already decided by Mrs. Armstrong. Feel free to comment on anything that might be wrong about the lesson. :) Thanks!

Okay, so the notes on this were basically just examples and Mrs.Amrstrong explained them to us, so I tried to explain a bit of it in my own words.
Remember not to get confused with bases and coefficients. Also dont forget that to change a radical into rational exponent form, the root of the radical becomes the denomenator and the numerator is the exponent.
I know its not much, but if you guys have any questions, just comment and I will do my best to help =).

Hello, there Gummy Bears!!!
If you are still having some trouble with our topic, which is making radical exponents into rational numbers and vice-versa, I found a few videos that may help you. I hope it can assist you in some way. Ms. Armstrong assigned Exercise 26, ommiting #'s 8,9,12,15 and 19.
REMINDER: Quiz on tuesday!!!!
Anyway, who's the next blogger?
