Just about everyone here writes a power like this:
4x^2 which means 4x squared.
If you have a Windows computer, you could hold down the "ALT" key and at the same time, type in the number 0178 and you will get this ²
So then you could type 4x² just as it should appear.
Step-by-step explanation:
-8 and 8 would work :)
x=3 and y=2 because 6+6 = 12 and 2 times 3 is 6 :)
