so remember some exponentional laws


x^(m/n) = \sqrt[n]{x^m}


(x^n)/(x^m)=x^(n-m) and


x^(-n)= (1)/(x^(n))
so

4 to the 6th root=4^(1/6)
4 to the 3rd root=4^(1/3)

so

(4^(1/6))/(4^(1/3)) =4^((1/6)-(1/3))=4^((1/6)-(2/6))=4^(-1/3)
and
4^(-1/3)= (1)/(4^(1/3))= \frac{1}{ \sqrt[3]{4} }

the answer is
\frac{1}{ \sqrt[3]{4} }
