$${x}^{\mathrm{6039}} \left[\left(\frac{\mathrm{900}−\mathrm{1}}{\mathrm{100}}\right)\left(\frac{\mathrm{900}−\mathrm{2}}{\mathrm{100}}\right)…\left(\frac{\mathrm{900}−\mathrm{2013}}{\mathrm{100}}\right)\right]^{\mathrm{3}} \\ $$$$=\frac{{x}^{\mathrm{6039}} }{\mathrm{10}^{\mathrm{12078}} }\left(\mathrm{899}\right)^{\mathrm{3}} \left(\mathrm{888}\right)^{\mathrm{3}} …\left(−\mathrm{1113}\right)^{\mathrm{3}} =\mathrm{0} \\ $$
