Answer: [tex]\bold{b)\quad \dfrac{4x^6z^4}{9y^4}}[/tex]
Step-by-step 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.
[tex]\dfrac{16x^{4}\cdot y^{-3}\cdot z^{4}}{36x^{-2}\cdot y^{1}\cdot z^{0}}\quad =\dfrac{16x^{4+2}\cdot y^{-3+3}\cdot z^{4}}{36x^{-2+2}\cdot y^{1+3}\cdot 1}\quad =\large\boxed{\dfrac{4x^6z^4}{9y^4}}[/tex]
