Very large or very small numbers are best input with exponential notation. For instance, the number 8,000,000 (eight million) is

Lerok [7]

Answer:

$9*10^{12}km$

Step-by-step explanation:

$9,460,730,472,580.8 km$

First, we can work out 5% of our number, by multiplying it by 0.05

$9,460,730,472,580.8 * 0.05 = 473,036,523,629$

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

$9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}$

We can see that $9*10^{12}$ is in the range of valid answers, as:

$8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}$

So, our final answer is:

$9*10^{12}km$
