Answer:
Q1) y= 2
Q2) y= 4
Step-by-step explanation:
Q1) If you sub in x as -1, 2 to the power of -1 is 0.5. You always solve the power first, not the multiplication. So then you do 0.5 times 4 and you get 2.
Q2) If you sub in x as 0, anything to the power of 0 becomes 1. 2 to the power of 0 is 1. Then you do the multiplication, 4 times 1 = 4

Answer:
![7xy^{2} \sqrt[3]{2xy}](https://tex.z-dn.net/?f=7xy%5E%7B2%7D%20%5Csqrt%5B3%5D%7B2xy%7D)
Step-by-step explanation:
![\sqrt[3]{686x^{4} y^{7}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B686x%5E%7B4%7D%20y%5E%7B7%7D%7D)



![\sqrt[3]{343} =7](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B343%7D%20%3D7)
= 
so you're left with 2, x, and y inside the cube root, and 7, x, and y^2 outside
![7xy^{2} \sqrt[3]{2xy}](https://tex.z-dn.net/?f=7xy%5E%7B2%7D%20%5Csqrt%5B3%5D%7B2xy%7D)
