16*x^(10/3)*y^(8/3)*z^(2/3).

Explanation:

Expression =(64x^5y^4z)^(2/3)= (64^(2/3))(x^5)^(2/3)* (y^4)^(2/3)*z^(2/3), .............[Rule : (ab)^n=a^n*b^n]
=(4^3)^(2/3)*x^(5*2/3)*y^(4*2/3)*z^(2/3),........[Rule :(a^m)^n=a^(mn)]
=4^(3*2/3)*x^(10/3)*y^(8/3)*z^(2/3)=4^2*x^(10/3)*y^(8/3)*z^(2/3)=16*x^(10/3)*y^(8/3)*z^(2/3).
