  (a)\: 8\times 10^{4}+6\times 10^{3}+0\times 10^{2}+4\times 10^{1}+5\times 10^{0}

             =8\times 10000+6\times 1000+0\times 100+4\times 10+5\times 1

           =80000+6000+000+40+5

           =86045

 (b)\: 4\times 10^{5}+5\times 10^{3}+3\times 10^{2}+2\times 10^{0}

          =4\times 100000+0\times 10000+5\times 1000+3\times 100+0\times 10+2\times 1

           =400000+00000+5000+300+00+2

           =405302

         (c)\: 3\times 10^{4}+7\times 10^{2}+5\times 10^{0}

   =3\times 10000+0\times 1000+7\times 100+0\times 10+5\times 1

           =30000+0000+700+00+5

           =30705

         (d)\: 9\times 10^{5}+2\times 10^{2}+3\times 10^{1}

=9\times 100000+0\times 10000+0\times 1000+2\times 100+3\times 10+0\times 1

=900000+00000+0000+200+30+0

 =900230

 

Thus, the above problems are simplified in simpler forms.
