Answer:


(2)/(3)

Explanation:


\sqrt[4]{(16)/(81) }

Firstly, we want to get rid of the '
\sqrt[4]{}'. One way to get rid of a root is by apply the rule
\sqrt[n]{x^(n) } =x. If we could represent the term inside the root in index form to the power of 4, we could cancel out the '
\sqrt[4]{}'.

So let's try represent the terms in the fraction in index form to the power of 4. It may be helpful to recall the rule
(x^(m))^(n)=x^(mn).


16=4^(2)= (2^(2))^(2) =2^(4)


81=9^(2)=(3^(2))^(2)=3^(4)

So now we can rewrite
\sqrt[4]{(16)/(81) } as
\sqrt[4]{(2^(4) )/(3^(4) ) } or
\sqrt[4]{((2)/(3) )^(4) }. Now we can canel the power of 4 and the '
\sqrt[4]{}' to get:
(2)/(3)
