Answer:
![\dfrac{m^3}{16p^2q^2}](https://tex.z-dn.net/?f=%5Cdfrac%7Bm%5E3%7D%7B16p%5E2q%5E2%7D)
Step-by-step explanation:
Given:
![(2pm^{-1}q^0)^{-4}\cdot \dfrac{ 2m^{-1} p^3}{2pq^2}](https://tex.z-dn.net/?f=%282pm%5E%7B-1%7Dq%5E0%29%5E%7B-4%7D%5Ccdot%20%5Cdfrac%7B%202m%5E%7B-1%7D%20p%5E3%7D%7B2pq%5E2%7D)
1.
![m^{-1}=\dfrac{1}{m}](https://tex.z-dn.net/?f=m%5E%7B-1%7D%3D%5Cdfrac%7B1%7D%7Bm%7D)
2.
![q^0=1](https://tex.z-dn.net/?f=q%5E0%3D1)
3.
![2pm^{-1}q^0=2p\cdot \dfrac{1}{m}\cdot 1=\dfrac{2p}{m}](https://tex.z-dn.net/?f=2pm%5E%7B-1%7Dq%5E0%3D2p%5Ccdot%20%5Cdfrac%7B1%7D%7Bm%7D%5Ccdot%201%3D%5Cdfrac%7B2p%7D%7Bm%7D)
4.
![(2pm^{-1}q^0)^{-4}=\left(\dfrac{2p}{m}\right)^{-4}=\left(\dfrac{m}{2p}\right)^4=\dfrac{m^4}{(2p)^4}=\dfrac{m^4}{16p^4}](https://tex.z-dn.net/?f=%282pm%5E%7B-1%7Dq%5E0%29%5E%7B-4%7D%3D%5Cleft%28%5Cdfrac%7B2p%7D%7Bm%7D%5Cright%29%5E%7B-4%7D%3D%5Cleft%28%5Cdfrac%7Bm%7D%7B2p%7D%5Cright%29%5E4%3D%5Cdfrac%7Bm%5E4%7D%7B%282p%29%5E4%7D%3D%5Cdfrac%7Bm%5E4%7D%7B16p%5E4%7D)

![m^{-1}=\dfrac{1}{m}](https://tex.z-dn.net/?f=m%5E%7B-1%7D%3D%5Cdfrac%7B1%7D%7Bm%7D)
6.
![2m^{-1} p^3=2\cdot \dfrac{1}{m}\cdot p^3=\dfrac{2p^3}{m}](https://tex.z-dn.net/?f=2m%5E%7B-1%7D%20p%5E3%3D2%5Ccdot%20%5Cdfrac%7B1%7D%7Bm%7D%5Ccdot%20p%5E3%3D%5Cdfrac%7B2p%5E3%7D%7Bm%7D)
7.
![\dfrac{ 2m^{-1} p^3}{2pq^2}=\dfrac{\frac{2p^3}{m}}{2pq^2}=\dfrac{2p^3}{m}\cdot \dfrac{1}{2pq^2}=\dfrac{p^2}{mq^2}](https://tex.z-dn.net/?f=%5Cdfrac%7B%202m%5E%7B-1%7D%20p%5E3%7D%7B2pq%5E2%7D%3D%5Cdfrac%7B%5Cfrac%7B2p%5E3%7D%7Bm%7D%7D%7B2pq%5E2%7D%3D%5Cdfrac%7B2p%5E3%7D%7Bm%7D%5Ccdot%20%5Cdfrac%7B1%7D%7B2pq%5E2%7D%3D%5Cdfrac%7Bp%5E2%7D%7Bmq%5E2%7D)
8.
![(2pm^{-1}q^0)^{-4}\cdot \dfrac{ 2m^{-1} p^3}{2pq^2}=\dfrac{m^4}{16p^4}\cdot \dfrac{p^2}{mq^2}=\dfrac{m^3}{16p^2q^2}](https://tex.z-dn.net/?f=%282pm%5E%7B-1%7Dq%5E0%29%5E%7B-4%7D%5Ccdot%20%5Cdfrac%7B%202m%5E%7B-1%7D%20p%5E3%7D%7B2pq%5E2%7D%3D%5Cdfrac%7Bm%5E4%7D%7B16p%5E4%7D%5Ccdot%20%5Cdfrac%7Bp%5E2%7D%7Bmq%5E2%7D%3D%5Cdfrac%7Bm%5E3%7D%7B16p%5E2q%5E2%7D)
The answer is 169 ..... I hope this helps :)
