  • Radical expressions can often be simplified by moving factors which are perfect roots out from under the radical sign.

    This was very very helpful to me. I was having trouble with radicals in a practice SHSAT textbook and I looked up videos on radical. This came up and I decided to check it out. It helped me so much! What could have taken me 30 minutes to 45 to figure out instead took me 10 minutes and I finished 12 questions with confidence because I actually understood what I was doing. This also gave me the basic knowledge that my teachers haven't given me. I recommend this video to anyone having trouble with simplifying radical expressions.

    For those who didn't get it
    Example: √126
    First do prime factorisation
    2 |126
    3 | 63
    3 | 21
    7
    * Now √126=2•3•3•7
    = 2•3²•7
    (Take the squared digits outside)
    = 3²√2•7
    √126 = 3√14
    (Hope you get it 🙂)

      my same problem how do you get these numbers to 3675 / 300 how ??????

    • @SKlDROW
      @SKlDROW Před 5 lety +12

      The way I figured it out is by taking 3675 and dividing it by 5 as a start. I did this because I know that dividing 3675 by 5 will result in a whole integer.
      3675 / 5 = 735... 735 can be further divided
      735 / 5 = 147... 147 can be divided
      147 / 3 = 49... 49 can be divided again
      49 / 7 = 7... 7 can be divided once more
      7 / 7 = 1... and this is where we stop
      So now we take all of the numbers that were used in breaking 3675 into 1, so that is 5, 5, 3, 7, 7.
      Now that the pieces are together, we can simplify the √3675 into √5*5*3*7*7
