Question

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

Answer 1

Wouldn't it be C?

Answer 2

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

Answer 3

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

Answer 4

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

100/200 = 1/2

Answer 5

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

Answer 6

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

can you post a screenshot?

Answer 20

thanks

Answer 21

No problem

Answer 22

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

Answer 23

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

Answer 24

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

Answer 25

So what one should I put down

Answer 26

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

Answer 27

Okay thank you

Answer 28
