Wouldn't it be C?

- anonymous

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

- jim_thompson5910

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

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.:/

- 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?

- anonymous

how do you do that

I have no way to

thanks

No problem

- 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

- anonymous

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

- jim_thompson5910

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

- anonymous

So what one should I put down

- 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

- anonymous

Okay thank you

- jim_thompson5910

no problem
