Solution:
- $ [{{(165)}^{2}}/75\times 12]/36={{(?)}^{2}} $
$ \Rightarrow $ $ [ \frac{{{(165)}^{2}}}{75}\times 12 ]/36={{(?)}^{2}} $
$ \Rightarrow $ $ [ \frac{165\times 165}{75}\times 12 ]/36={{(?)}^{2}} $
$ \Rightarrow $ $ [ \frac{165\times 11}{5}\times 12 ]/36={{(?)}^{2}} $
$ \Rightarrow $ $ [33\times 11\times 12]/36={{(?)}^{2}} $
