Scientific notation<span> is the way that scientists easily handle very large numbers or very small numbers.

For example, instead of writing 0.0000000056, we write </span> $5.6 * 10^{-9}$ .

Hence, in scientific notation

0.000028 = $2.8 * 10^{-5}$

So, the answer is -5. The power of ten has to be -5.

-5 as that you would have to count that places to the left. You end decimal would have to be between 1 and 10, so it would not count the 8. I'm sorry if my explanation is not good, but that is the right answer

Hiya! Here's my question:

Step2247 [10]

wait i got it!

Since 18 kilograms are 18000 grams, you have

18000/30=600

and

800/30=26.6

So, with 18 kilograms of salt the baker can make exactly 600 batches with no leftovers, while with 800 grams of salt the baker can make 26 batches, with some leftovers.

In fact, 26 batches require

26 x 30 =780

grams of salt, and the remaining

800-780=20

grams of salt are not enought to prepare the next batch
