Hello, I have two more rational exponent question that I wanted to verify please:

4x^3y^-2
_________
2x^-1y^4

= 2x^4y^6

is this correct?

2nd question:

[w^1 / w^-3]

my answer:

= [w^(1)(-4)/ w ^ (-3)(-4)]
= w^-4 / w^12
= w^12 / w^4
= w^3 / w

Is this right?

Both are wrong. You seem to have no idea at all how to handle exponents.

The answers are
2x^4 y^-6 and w^4.

Well aren't you special to tell me that. You seem to have no idea how to treat people. Hmmm, which deficite would I rather have. Thanks for the disrespectful help. I don't think you should tutor anyone.
