How much zeros has the number $1000!$ at the end?

.1 If a number ends with n n zeros than it is divisible by 10n 10 n, that is 2n5n 2 n 5 n. A factorial clearly has more 2 2 s than 5 5 s in its factorization so you only need to count

What does it mean when something says (in thousands)

.It means quot;26 million thousandsquot;. Essentially just take all those values and multiply them by 1000 1000. So roughly $26 $ 26 billion in sales.

algebra precalculus - Partitions using only powers of two on $1000 ...

How many ways are there to write $1000$ as a sum of powers of $2,$ ($2^0$ counts), where each power of two can be used a maximum of $3$ times. Furthermore, $1+2+4+4$ is the
