Answer:
If you are to express 5000 in scientific notation form, it would be:
5 · 
Step-by-step explanation:
Looking at it, there is only 1 sig fig (significant figure) and this means if you are to change it to number from between 1 - 10
it would be: 5
so it would look like 5.000 or just 5.
5,000. vs. 5.000 are both completely different things, that are expressed in different ways. But in this case, you can see that we have move the decimal place 3 times, which is why we have
That is how you get your answer!
∛125x^21y^24
Split them up:
∛125 * ∛x^21 * ∛y^24
∛125 = 5
∛x^21 = x^7 21/3 = 7
∛y^24 = y^8 24/3 = 8
The simpler form of the radical expression: ∛25x^21y^24 is: <span>D. 5x^7y^8</span>

Answer:
380 different ways
Step-by-step explanation:
We can solve this problem using a permutation formula, as the order in a group of two students matter.
So, for this problem, we have 20 students and want to form groups of 2, so we have a permutation of 20 choose 2:
P(20,2) = 20! / (20-2)! = 20! / 18! = 20 * 19 = 380 different ways
Another way to solve this problem is:
For the first student being chose, we have 20 students available, and for the second student, we have just 19, as one was already chose, so the number of ways to choose these two students is 20 * 19 = 380
