Answer:
I’m lost
Step-by-step explanation:
The expression can be solved by expanding the bracket and multiplying out the terms
![(p^4-q^4)(p^4+q^4)](https://tex.z-dn.net/?f=%28p%5E4-q%5E4%29%28p%5E4%2Bq%5E4%29)
![\begin{gathered} =p^4(p^4+q^4)-q^4(p^4+q^4) \\ =p^8+p^4q^4-p^4q^4-q^8 \\ =p^8-q^8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3Dp%5E4%28p%5E4%2Bq%5E4%29-q%5E4%28p%5E4%2Bq%5E4%29%20%5C%5C%20%3Dp%5E8%2Bp%5E4q%5E4-p%5E4q%5E4-q%5E8%20%5C%5C%20%3Dp%5E8-q%5E8%20%5Cend%7Bgathered%7D)
Therefore, the expression can be simplified as;
![p^8-q^8](https://tex.z-dn.net/?f=p%5E8-q%5E8)
Alternatively, using the theorem of difference of two squares, which is
![a^2-b^2=(a-b)(a+b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29)
Hence,
![p^8-q^8=(p^4)^2-(q^4)^2](https://tex.z-dn.net/?f=p%5E8-q%5E8%3D%28p%5E4%29%5E2-%28q%5E4%29%5E2)
1/4=.25
