Question 568222
Divide and simplify.
4.) ∛270x / ∛10xy^2
= {{{root(3,(270x/10xy^2))}}}
= {{{root(3,(27/y^2))}}}
= {{{root(3,(27y/y^3))}}}
= {{{3*root(3,(y))/y}}}


Rationalize the denominator of each expression.
5.) {{{sqrt(7x)/sqrt(3) = sqrt(21x)/sqrt(9)}}}
= {{{sqrt(21x)/3}}}
------------------------------
6.) {{{root(3,x^2)/root(3,4)}}}
= {{{root(3,2x^2)/root(3,8)}}}
= {{{root(3,2x^2)/2}}}
