Very large or very small numbers are best input with exponential notation. For instance, the number 8,000,000 (eight million) is equal to 8×106 . In this course, you can enter that as either 8 * 10 ^ 6 or as 8e6 in these problems. Try out exponential notation in the question below. One light year is equal to 9,460,730,472,580.8 kilometers. Enter this number below in exponential notation. The tolerance on this question is 5%. ________km

<div class = 'in102'><p><strong>Answer:</strong></p><p>$9*10^{}12{}km$</p><p></p><p><strong></strong></p><p>$9,460,730,472,580.8 km$</p><p>First, we can work out 5% by multiplying our numbers.0.05</p><p>$9,460,730,472,580.8 * 0.05 = 473,036,523,629$</p><p></p><p>Now, if we add or subtract 5% of what we calculated from the original number, we can calculate the minimum and maximum of our final answer in that range.</p><p>$9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{}12{}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{}12{}$</p><p></p><p>we can see that $9*10^{}12{}$ Within the scope of effective answers, such as:</p><p> $8.9*10^{}12{} \leq 9*10^{}12{} \leq 9.9 * 10^{}12{}$</p><p></p><p>so, our final answer is:</p><p>$9*10^{}12{}km$</p>
