SOLUTION: Find the value of m and n if {{{(125^(1/2)+(5/64)^(-1/2)-sqrt(5)*(25/16)^(3/4))*(2/(sqrt(5)+2))=(2/5)(m+n*sqrt(5))}}}.

1 equation in 2 variables has no unique solution.
============
You can let m = 0 (or other value) and solve for n, or vice versa.

Find the value of m and n if
(125^(1/2)+(5/64)^(-1/2)-sqrt(5)*(25/16)^(3/4))*(2/(sqrt(5)+2)) =
(2/5)(m+n*sqrt(5))
========
(5sqrt(5) + 8/sqrt(5) - sqrt(5)*sqrt(5)/2 * (2(sqrt(5)-2)/(1))
= (2/5)(m+n*sqrt(5))
------
(13sqrt(5) - (5/2)*(2sqrt(5)-4) = (2/5)m + (2sqrt(5)/5)n
--------
13sqrt(5) - 5sqrt(5)-10 = (2/5)m + (2/5)sqrt(5)n
----
8sqrt(5) - 10 = (2/5)m + (2/5)sqrt(5)n
-------------------
(2/5)m = 10 and (2/5)sqrt(5)n = 8sqrt(5)
m = 25 and (2/5)n = 8
m = 25 and n = 20
----------------------
