Simplifying, Adding, Subtracting, and Multiplying Radical Expressions

QuestionAnswer
What are radicals? An expression that has a square root, cube root, etc. The symbol is √.
Are powers and radicals similar? Yes, you can undo a power with a radical. Just think 2 to the second power is 4. However, the square root of 4 is 2.
Why is it important to simplify radicals? When radicals are simplified it makes it easier to solve and understand complex problems. Just think would it be easier to understand the square root of 3675 or 35 times the square root of 3?
How do you find the square root of big numbers? Break them down! Find the prime factorization.
How do you simplify the radical 3675? Find the prime factorization.You should get 7x7x5x5x3. Since 7 and 5 are both to the second power the will go outside of the radical (undone) while the 3 will remain under the radical. Multiply the 7 and 5 and the answer should be 35 times the root of 3

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
