Answer:
1. -8/11
2. -1 3/7
Step-by-step explanation(Q1):
Using order of operations, start with parentheses and work with exponents second. Then, M/D/A/S.
![5-3\\=2\\=2^(3)\\=\boxed{8}\\3^2\\=9\\=1+9-21\\1+9\\=10\\=10-21\\=\boxed{-11}\\=(8)/(-11)](https://img.qammunity.org/2023/formulas/mathematics/high-school/zfglsu7w1jv3yxfwg6txaxxpxg0fsd5hpl.png)

Step-by-step explanation(Q2):
Given x = 3, y = -2
![4\left(3\right)\\=12\\=12+\left(-2\right)\\12+\left(-2\right)\\=12-2\\=10\\\downarrow\\2\left(-2\right)\\=-4\\=-4-3\\=\left(-4\right)-3\\=-7\\=(10)/(-7)\\=-(10)/(7)\\\\\bold{Long~Division}\\7 / 10 = 1\\1 * 7 = 7\\7 - 10 = 3\\= 1,R3\\\\(10)/(7)\\=1(3)/(7)\\=-1(3)/(7)](https://img.qammunity.org/2023/formulas/mathematics/high-school/pgre381ke7tgzn0obipeumt02yudczxmd6.png)
