#1**+2 **

Alright, let's break this down by simplifying it.

\((6x+1/3x)^2 \)

\(=(6x+\frac{1}{3x})^2\)

Now we can apply the formula

\((a+b)^2=a^2+2ab+b^2\)

or in this case,

\((6x + \frac{1}{3x})^2 = 6x^2+2(6x)\frac{1}{3x}+\frac{1}{3x}^2\)

which will become:

6x^2 + 4 + 1/3x^{2}, since 2*6x is 12x, and 12x+1/3x is 12x/3x. Divide by 3x and you get the answer, \(\fbox{4}\)

Ah. I constantly forget to pay attention to the details. Thanks for the heads up!
