3 During the first year of operation, a company produced 8.4times 10^9 reams of paper.During the second year,the company produced 5.6 times the number of reams of paper that it produced during the first year. Which expression represents the number of reams of paper the company produced during the second year? 1.5times 10^9 B 1.5times 10^10 4.704times 10^9 D. 4.704times 10^10

To find the number of reams of paper produced during the second year, we need to multiply the number of reams produced during the first year by 5.6.<br /><br />Given that the company produced $8.4\times 10^{9}$ reams of paper during the first year, we can represent the number of reams produced during the second year as:<br /><br />$5.6 \times (8.4\times 10^{9})$<br /><br />Now, let's calculate this expression:<br /><br />$5.6 \times (8.4\times 10^{9}) = 5.6 \times 8.4 \times 10^{9} = 47.04 \times 10^{9} = 4.704 \times 10^{10}$<br /><br />Therefore, the expression that represents the number of reams of paper the company produced during the second year is:<br /><br />D. $4.704\times 10^{10}$
