Step-by-step explanation:

Since f(x) = 4 + and g(x) = ,

(f g) (x) = f( x ) * g( x ) = ( 4 + ) ( +4 )^(1/2)

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

can you rephrase the question ? it is unclear : -)
