    I have this equation, its 3 square root symbol 27/y^6

    3sqrt(27) -------- ?? y^6

    so the y^6 is not part of the radical correct?

    for clarification: \[\frac{3\sqrt{27}}{y^6}\]

    and you want to "simplify" perhaps?

    sqrt(27) = sqrt(3*3*3) = sqrt(3^2) sqrt(3) = 3sqrt(3) 3*3sqrt(3) 9sqrt(3) --------- = -------- y^6 y^6

    most math notation has something that will undo it; the relationship between sqrt and ^2 cancel each other out

    so if you can determine a value in the sqrt(...) that can be factored as a ^2; go for it

    to make it easier to read: sqrt(27) sqrt(3*3*3) sqrt(3^2) * sqrt(3) 3 * sqrt(3)

  17. monika3466

    so now, it becomes 9 sqrt(3) ------- y^6

    ok, cool... i have another one too... its the square root symbol 9x^6 ----- 64y^3

    sqrt(filler) is more readable

    sqrt(9 x^6) ---------- ; like thgis? 64 y^3

    you should keep in mind that multiplication can split a radical like this: sqrt(9 x^6) sqrt(9) sqrt(x^6) ; now we can work on each of these in their own right

    what does sqrt(9) equal?

  26. monika3466
    • 3 years ago

    is it 3

  27. amistre64
    • 3 years ago
    Best Response

    Medals 1

    3 it is; and for the x^6 part we have to know something about exponents. sqrt is another name for ^(1/2); which means sqrt(x^6) = x^(6/2) = x^3 altogether we get: 3 x^3 ------ 64 y^3

  28. monika3466
    • 3 years ago
    Best Response
    You've already chosen the best response.
    Medals 0

    ok, so now we try to find the square root of 64; right?

  29. monika3466

    ok.. i think i get it

  30. monika3466
    • 3 years ago
    Best Response
    You've already chosen the best response.

    so its 3x^3 ----- 8y^3

  31. monika3466
    • 3 years ago

    You've already chosen the best response.

    is that the final answer or is there more to simplify?

  32. amistre64
    • 3 years ago

    if 64 is included in the radical; thats the umbrella of the sqaure root sign, then you would most likely convert it to 8 yes ... otherwise, leave it as is
