Therefore, the hundreds digit is (D)6. Sidenote: By Euler's Totient Theorem, aϕ(1000)≡a(mod1000) for any a, so a400≡a(mod1000) and 112011≡1111(mod1000). We can then proceed using the clever application of the Binomial Theorem. We need to compute 20112011(mod1000). By the Ch...
We have:11^(2011)=1+2011⋅10+(2011⋅2010)/2⋅100=1+20110+(11⋅10)/2⋅100=1+20110+5500=1+110+500=611(mod1000).Therefore, the hundreds digit is (D)6.Sidenote: By Euler's Totient Theorem, a^0(1000)=a(mod1000) for any a,so a^(400)=a(mod1000) and 11^2(11...
