F(x) = x 
g(x) = raíz cuadrada de x = x^(1/2) 

1) (g+f) · (3) = 
=  [ x^(1/2) + x ] · 3 = 
= 3 · x^(1/2) 

2) (f + g) · (x) = 
=  [x +  x^(1/2) ]  · x = 
= [ x ^ (1/2) ] · x = 
= x ^ [(1/2) + 1 ] = 
= x ^ [ (1+2)/2]= 
= x ^ 3/2

3) (g - f) · (x) = 
=  [ x^(1/2) - x ]  · x = 
= x ^ (1/2) · x = 
= x ^ [ (1+2)/2]= 
= x ^ 3/2
