Answer:
The answer is 0.25.
Step-by-step explanation:
First, you have to get of the negative from the power using Indices Law, a^-n = 1/a^n :
![{2}^{ - 2}](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B%20-%202%7D%20)
![\frac{1}{ {2}^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%7B2%7D%5E%7B2%7D%20%7D%20)
Next, you can evaluate :
2² = 2×2
= 4
1/2² = 1/4
= 0.25
X is equal to 10 and y is equal to 2.
