Answer:

see below

Explanation:

Problem-1:


{x}^{ (2)/(7) }

remember that,


\displaystyle {x}^{ (a)/(b) } = \sqrt[b]{ {x}^(a) }

here,

  • a=2
  • b=7

hence,


{x}^{ (2)/(7) } = \boxed{\sqrt[7]{ {x}^(2) } }

Problem-2:

recall that,


\sqrt[n]{x} = {x}^{ (1)/(n) }

therefore,


\sqrt[3]{2y} = (2y {)}^{ (1)/(3) } \implies \boxed{{2 }^{ (1)/(3) } {y}^{ (1)/(3) } }

\\ \rm\dashrightarrow x^{(2)/(7)}


\\ \rm\dashrightarrow x^(2(1/7))


\\ \rm\dashrightarrow \sqrt[7]{x^2}

And


\\ \rm\dashrightarrow \sqrt[3]{2y}


\\ \rm\dashrightarrow 2y^{(1)/(3)}
