6^{2}\left(\sqrt{85}\right)^{2}=\left(\sqrt{36x}\right)^{2}
Expand \left(6\sqrt{85}\right)^{2}.
36\left(\sqrt{85}\right)^{2}=\left(\sqrt{36x}\right)^{2}
Calculate 6 to the power of 2 and get 36.
36\times 85=\left(\sqrt{36x}\right)^{2}
The square of \sqrt{85} is 85.
3060=\left(\sqrt{36x}\right)^{2}
Multiply 36 and 85 to get 3060.
3060=36x
Calculate \sqrt{36x} to the power of 2 and get 36x.
36x=3060
Swap sides so that all variable terms are on the left hand side.
x=\frac{3060}{36}
Divide both sides by 36.
x=85
Divide 3060 by 36 to get 85.
