Answer
$\frac{3}{4}$
Work Step by Step
To simplify the second term, take the fifth root, square it, and then take its inverse. In this case, the fifth root is 2, so square 2 to get 4. Finally, take its inverse. Then simplify the rest of the problem.
$(\frac{2}{7})^0-32^{-\frac{2}{5}}$
$1-\frac{1}{4}$
$\frac{3}{4}$
