for example lets use 3^2 + 4^2, you add the main numbers, 3 and 4 to get 7, then there are still the exponents, the squared signs, they don't change, they stay as a two. If your problem required a single whole number, then you have to square the 7, 7*7 is 49, so that or 7^2 would be your final answer.
Step-by-step explanation:
(x + y , x - y) = (4 , 2)
x+y=4 ------(1)
x-y=2 ------(2)
_____ (adding two equation)
2x=6
x=3
From equation 1
3+y=4
y=1
