(ii) $9\times {10}^6+7\times {10}^5+0\times {10}^4+3\times {10}^3+4\times {10}^2+6\times {10}^1+2\times {10}^0$
(iii) $8\times {10}^5+6\times {10}^4+4\times {10}^3+2\times {10}^2+9\times {10}^1+6\times {10}^0$

Answer 1

(i) $6\times {10}^4+3\times {10}^3+0\times {10}^2+7\times {10}^1+8\times {10}^0$

$=6\times 10000+3\times 1000+0\times 100+7\times 10+8\times 1$

$=63078$

(ii) $9\times {10}^6+7\times {10}^5+0\times {10}^4+3\times {10}^3+4\times {10}^2+6\times {10}^1+2\times {10}^0$

$=9\times 1000000+7\times 100000+0\times 10000+3\times 1000+4\times 100+6\times 10+2\times 1$

$=9703462$
(iii) $8\times {10}^5+6\times {10}^4+4\times {10}^3+2\times {10}^2+9\times {10}^1+6\times {10}^0$

$=8\times 100000+6\times 10000+4\times 1000+2\times 100+9\times 10+6\times 1$

$=864296$
