Answer
$25,500,000,000$ unit cases
Work Step by Step
We are given that the Coca-Cola Company sold $2.55\times10^{10}$ unit cases of beverages worldwide. Since the exponent is positive, move the decimal 10 places to the right.
Note that 10 places to the right will be 8 decimal places past the last digit (5), so we will add 8 zeroes after 5.
$2.55\times10^{10}=25,500,000,000$ unit cases
