To solve the equation \(36x^2 = 0\), we first divide both sides by \(36\), resulting in:
\[ x^2 = 0 \]
Taking the square root of both sides gives:
\[ x = 0 \]
Thus, the solution set contains only the value 0. In set notation, the solution set is expressed as:
\[ {0} \]
Therefore, the correct response is:
\({0}\)
