## anonymous one year ago This confuses me. Can you help for a medal? What is the simplified expression for 5^-3 • 2^2 • 5^5 over 2^3 • 5^2 2^2 over 5^2 5 over 2^2 5 over 2 5^2 over 2

1. anonymous

Wouldn't it be C?

2. anonymous

I'm thinking it would be C or D? Can someone please confirm

3. jim_thompson5910

There seems to be a typo. I'm getting a different answer which isn't in the list of choices.

4. jim_thompson5910

5^(-3)*2^2*5^5 = 100 2^3*5^2 = 200 100/200 = 1/2

But I don't have that as any choices.:/

6. jim_thompson5910

you're absolutely sure the problem is 5^-3 • 2^2 • 5^5 over 2^3 • 5^2 ? can you post a screenshot?

7. anonymous

how do you do that

8. anonymous

I have no way to

9. jim_thompson5910

go here http://www.take-a-screenshot.org/ it's a website that has instructions on how to take a screenshot (it varies for different computers)

Otai one sec ty

But they want the simplified fraction, not fully solved

13. jim_thompson5910

there's no attach file button below the text box?

14. anonymous

That's why I think it would be c

15. anonymous

No

16. jim_thompson5910

can you upload the pic to something like imgur? then host the link

thanks

No problem

22. jim_thompson5910

ok so yeah, it looks like $\Large \frac{5^{-3}\cdot 2^2 \cdot 5^5}{2^3 \cdot 5^2}$ but the problem is that none of the answer choices come up This is what I get $\Large \frac{5^{-3}\cdot 2^2 \cdot 5^5}{2^3 \cdot 5^2}$ $\Large \frac{5^{-3+5}\cdot 2^2}{2^3 \cdot 5^2}$ $\Large \frac{5^{2}\cdot 2^2}{2^3 \cdot 5^2}$ $\Large \frac{2^2}{2^3}$ $\Large \frac{4}{8}$ $\Large \frac{1}{2}$ So strange how 1/2 isn't in the list

That's what confuses me on why I'm not sure /:

24. jim_thompson5910

this is just one of those problems where they messed up big time

25. anonymous

So what one should I put down

26. jim_thompson5910

I'm not sure. Any seem likely as to what they meant to say. You'll have to ask your teacher about it since s/he will know what to do. Most likely, the teacher will give you free points back for this one since it's unfair

27. anonymous

Okay thank you

28. jim_thompson5910

no problem
