simplify the expression

(the 7th root of 11x/y^6)(the 7th root of y^6/11x^8)

the root is over the whole fraction in both cases.

I've already done the problem once and got x(the 7th root of 1/x). which apparently this is wrong.

  1. when multiplying roots, take the root of the product. You then have

    7throot( (11x/y^6) * (y^6/11x^8) )
    = 7throot(1/x^7)
    = 1/x

    It would help if you showed your work...
