I think B

HanAkoSolo (jamierox4ev3r):

Think again.

HanAkoSolo (jamierox4ev3r):

Recall that 8 can be turned into an exponent that has the same base, so you'll be able to subtract the exponents.

OpenStudy (itrymath):

C

HanAkoSolo (jamierox4ev3r):

See the rule that I posted in the pic. above (that is Quotient of Powers). :) And yup, C is correct!

HanAkoSolo (jamierox4ev3r):

Hope you found that helpful ^.^

OpenStudy (itrymath):

YAYY! Well im going to look at it because i guessed C

HanAkoSolo (jamierox4ev3r):

Haha alright :)

HanAkoSolo (jamierox4ev3r):

I can explain further if you have anymore questions :)

OpenStudy (itrymath):

please explain

HanAkoSolo (jamierox4ev3r):

okay. So 8 is equivalent to \(2^3\) So if you use this, your problem would turn into this: \(\Large\frac{2^5}{2^3}\) So do you see how the bases are both 2?

OpenStudy (itrymath):

Oh okay i sseeee

OpenStudy (itrymath):

OOOOOOo okay okay i understand now

OpenStudy (itrymath):

no need for any further explanations...

OpenStudy (caozeyuan):

you could argue for A though I guess, because you are technically adding the two exponents 5 and -3 to get 2

HanAkoSolo (jamierox4ev3r):

so you subtract the exponents! :) Glad to be of service :)

OpenStudy (itrymath):

thanks you!

HanAkoSolo (jamierox4ev3r):

welp, adding the exponents would be what you do for the Product of Powers. Quotient of powers is when you subtract, so I'm fairly certain that C. is the answer

OpenStudy (caozeyuan):

I mean A and C are really the same thing, it just depend on how you see things are you adding 5 and -3 or subtract 5 and 3

OpenStudy (itrymath):

a is incorrect you would need the answer to be 2^8

OpenStudy (itrymath):

o

OpenStudy (itrymath):

congrats on mathlete jamie

HanAkoSolo (jamierox4ev3r):

I mean, perhaps. But the rule of quotients is what makes C. the answer I'd choose without a doubt. And thanks! @ItryMath ! Although, I've been a mathlete for...quite a long time, LOL

OpenStudy (itrymath):

really, i thought you where a human calculator

OpenStudy (caozeyuan):

If this is an exam I would go for C too, just saying that its poorly worded so two answers both makes sense
