Answer 1

I wanna say A but it's been a while since I did those so maybe wait for another person who has a better understanding (•‿•)

Answer 2

Answer:
`\bold{b)\quad (4x^6z^4)/(9y^4)}`

Explanation:

If an exponent is negative, add the opposite to create an exponent of 0 (which equals 1). Make sure to balance the fraction by performing the same operation to the other side off the fraction bar.

`(16x^(4)\cdot y^(-3)\cdot z^(4))/(36x^(-2)\cdot y^(1)\cdot z^(0))\quad =(16x^(4+2)\cdot y^(-3+3)\cdot z^(4))/(36x^(-2+2)\cdot y^(1+3)\cdot 1)\quad =\large\boxed{(4x^6z^4)/(9y^4)}`
