Question 683208

Please, help me solve this equation.   Simplify the following. (81/625) raise to power -3/4. Thanks


{{{(81/625)^(-3/4)}}} ----- {{{1/(81/625)^(3/4)}}} ----- {{{(625/81)^(3/4)}}} ----- {{{(root(4, 625/81))^3}}} ----- {{{(5/3)^3}}} ----- {{{highlight_green(125/27)}}}, or {{{highlight_green(4&17/27)}}}
