(x3)(x4) is x7 because when you have a problem like that, you have to ADD your exponents.
-(m4)3 is -m12 since you're multiplying them.
(z3)5 is z15
y4 x y5 is y9
thats all i know of. hope it helps cx

Step-by-step explanation:
The remote interior angles of a triangle are basically the two angles that do not share a vertex with and are opposite to the exterior angle.
5. ∠1 and ∠2
6. ∠2 and ∠3
7. ∠1 and ∠3
Because the exterior angle of a triangle is equal to the remote interior angles we can set up the following equations:
8.
![x + 80 = 105 \\ x = 105 - 80 \\ x = 25](https://tex.z-dn.net/?f=x%20%2B%2080%20%3D%20105%20%5C%5C%20x%20%3D%20105%20-%2080%20%5C%5C%20x%20%3D%2025)
9.
x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
