Answer:

B.
x=(4)/(15)

Explanation:


  • (√(4-3x))/(√(3x) ) =2can be simplify by doing some algebra.
  • Particulary, in this case,
    (√(4-3x))/(√(3x) ) =\sqrt{(4-3x)/(3x) }, because of the distributive property with respect to division and multiplication.
  • Then, by dividing numerator and denominator by 3x inside the power we get
    \sqrt{((4)/(3x)-1)/(1)}=\sqrt{(4)/(3x)-1} =2.
  • To dispose of the squared root, we raise to power 2 both sides of the equation, to obtain the following expression:
    (4)/(3x)-1=4.
  • Finally, we just have to clear out the value of x from this expression, by addding 1 both sides of the equation:
    (4)/(3x)=5, and then by multiplying both sides by 3x, and then dividing the result by 15. This yields
    x=(4)/(15)
