K = 36^(1/2) + 64^(1/3) - (1/121)^-2 + (1/4)^-1 - 625^(1/4) 

K = 6 + 4 - 11 + 4 - 5 = -2 

----------------------------------------------------------------------------------------

x² - y³ - 5xy + 4x - 10

x = √2 ,   y = ³√-8 = -2 

x² = 2
y³ = -8 
-5xy = -5*√2*(-2) = 10√2
4x = 4√2

E = x² - y³ - 5xy + 4x - 10

E = 2 + 8 + 10√2 + 4√2 - 10

E = 14√2
