Question 319338
 the square root of 3x squared minus 4 square roots of 3 equals 0?
{{{sqrt(3x^2) - 4sqrt(3)}}} = 0
add {{{4sqrt(3)}}} to both sides
:
{{{sqrt(3x^2) = 4sqrt(3)}}} 
Square both sides
3x^2 = 16(3)
Divide both sides by 3
x^2 = 16
x = {{{sqrt(16)}}}
x = 4

Check solution in original equation
{{{sqrt(3(4^2)) - 4sqrt(3)}}} = 0
extract the square root
{{{4sqrt(3) - 4sqrt(3)}}} = 0
