Question 240498
Hint: Remember that {{{x^(1/2)^""=sqrt(x)}}}. So this means that {{{(4x)^(1/2)^""=x+8}}} is equivalent to {{{sqrt(4x)=x+8}}}



Square both sides to get {{{4x=(x+8)^2}}}. From here, you basically expand and then use the quadratic formula to solve for 'x'. Don't forget to check your answers.
