Answer 2

Step-by-step explanation:

(ii) 5 X 106 + 2 X 105 + 3 X 10 4+ 4 X 102 + 6 X 100

$(i)6 \times {10}^{4} + 9 \times {10}^{3} +7 \times 10 + 8 \times 100$

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

$= 60000 + 7000 + 800 + 70$

$= 67870$

$(ii)5 \times {10}^{6} + 2 \times {10}^{5} + 3 \times {10}^{4} + 4 \times {10}^{3} + 8 \times 100$

$= 5 \times 1000000 + 2 \times 100000 + 3 \times 10000 + 4 \times 1000 + 8 \times 100$

$= 5000000 + 200000 + 30000 + 4000 + 800$

$= 5234800$
