hey luigi how ya doin bud can you help?

luigi0210 · Answer

First thing, anything to the 0 is 1

anonymous · Answer

ik I jus put the problem up there as I saw it bc I didn't kno it

luigi0210 · Answer

you remember earlier how anything negative changes places?

anonymous · Answer

yes I wanted to say C but didn't know.. :(

anonymous · Answer

because the -1 was a +1

luigi0210 · Answer

$$\frac{ x^{-2}y^0 }{ 2^{-1}w^0z^3 }$$

anonymous · Answer

That the question just to simplify that

anonymous · Answer

Lap top died sorry for the delay

luigi0210 · Answer

Let's start by changing all those 0's to ones, so they basically don't exist leaving:
$$\frac{ x^{-2} }{ z^{-3}2^{-1} }$$

luigi0210 · Answer

ignore that negative z

luigi0210 · Answer

$$\frac{ x^{-2} }{ z^32^{-1} }$$

anonymous · Answer

Change the negative exponents to positive right?

luigi0210 · Answer

Yup, so do it and show me what you get

anonymous · Answer

X^2 over z^3 2^1

luigi0210 · Answer

Ah, remember that they switch too.. so it was ontop it would be on bottom and visa versa

anonymous · Answer

Which answer would it be though?

luigi0210 · Answer

It would be D

anonymous · Answer

Thanks bud
