What do you think?

anonymous · Answer

I don't know :(

anonymous · Answer

I think it is either c or D

igreen · Answer

Yep, good job eliminating A and B.

igreen · Answer

What do we do to the exponents when we divide?

igreen · Answer

Hint: When we MULTIPLY them, we add the exponents.

anonymous · Answer

we subtract the exponents

igreen · Answer

Dividing would be the opposite.

anonymous · Answer

right, so if we divide we subtract the exponents so the answer is D

igreen · Answer

Yep!

igreen · Answer

But D says to add them.

igreen · Answer

@kool_22

anonymous · Answer

D says the issue is that the exponents were added during division

igreen · Answer

Um, no..it's asking for the explanation..so it should be C, like you said, we subtract when dividing. @kool_22

anonymous · Answer

it says what is the first incorrect step @iGreen

igreen · Answer

Yes, but in Option D they don't add the exponents..

igreen · Answer

It's asking WHY it's incorrect..and it's incorrect because we subtract exponents when we divide.

igreen · Answer

Just trust me on this.

igreen · Answer

They added the exponents, and they didn't add them correctly..they were supposed to subtract the x's exponents together and subtract the y's exponents together.

But they added x to y and y to x.

anonymous · Answer

alrighty then I trust you. =) so it is C right? @iGreen I will let you know if it is wrong or right but I am starting to see your reasoning and you might be right.
