Simply Radical!The tale of square roots
Solve the following root:
Solve the following root:
Steps in Simplifying Square Roots
Factor the radicand using perfect squares.
Take the square root of the perfect square and leave the other factor inside as the radicand.
If you pull out a perfect square when another number is already in front of the square root, the two numbers are multiplied
Try it!
Multiplying Square Roots
Multiply the numbers outside the radical together and separately multiply the numbers inside the radicalSimplify using the prior method
How ‘bout it?
What about variables!!??
Write variables in long notationi.e:For every two variables inside the radical, one pulls out front of the radical.
Add/Subtract Roots
Rule: You can only add/subtract square roots if the two terms have the same radicand.
Simplify both square roots first and see if they combine
Example
Try it!
How ‘bout this one!
Remember FOIL?
Do Now: Multiply, then Simplify
Dividing Square Roots
QUE!!!
QUE!!!
Math is
Tangram Time!
See the power of the Square Root!!!
