Standard MCC8EEb

Simplify, Add, Subtract, Multiply, and Divide Radical Expressions

sometimes numbers under the radical sign disguise themselves
Sometimes numbers under the radical sign √, disguise themselves.
  • First---ALWAYS check to see if they are PERFECT SQUARES—if so, take them out of the radical sign.
  • Second—check their factors—in other words, what number times what number equals it.
  • Example----√8 is not perfect BUT you can break it into 4 x 2. AND….4 is PERFECT
      • SOOOOOOOOOOOOOOOOOOOOO
break it down
Break it down!
  • √8 = √4 x √2
  • Then-----√4 becomes a whole number 2
  • We write 2 √2.
  • Ta-dah!!!!! This is your answer!
another one
Another one
  • √12 = ? X ? where one of the numbers is a perfect square
  • That’s right---4 x 3
  • So, √4 x √3 = √12
  • Write √4 as 2 and leave √3 alone
your turn to practice
Your turn to practice
  • √18
  • √24
  • √28
  • √40
ok now just a bit harder
OK—now just a bit harder….
  • Sometimes you miss the largest square. If you do, don’t panic---
  • √72----most people say 9 x 8
  • √9 x √8 changes to 3 √8
  • BUT……..
watch carefully
Watch carefully
  • √8 breaks into 4 x 2
  • 3 √8 continues to break down
  • Change √8 to 2 √2----take the outside 2 and multiply it by the outside 3 to get 6.
  • Final answer-----6 √2
always check your answer
Always check your answer…..
  • 6 √2 means 6 x 6 = 36
  • 36 x 2 = 72----the number we started with
  • You try:
  • 2√8
  • 4 √12
  • 3 √18
the answers are
The answers are….
  • 2√8= 4√2
  • 4 √12=16√3
  • 3 √18= 9√2
now there is more to this
Now, there is more to this…
  • Multiplying radicals is easy—just put together what goes together and always check to see if you can reduce.
  • √8 x √3 = √24
  • √24 = 4 x 6
  • Change 4 into 2—leave the 6 in the crazy house
  • 2 √6
