x = 25^2 = 25*25 = 625.
Negative 5 to the second power would be -5 times -5 which would be 25.

25
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
Whatever equals 340
sorry I mean equals x
5 to the second power
25
25
52 = 25
Negative 5 to the second power would be -5 times -5 which would be 25.
It is: 5^2 = 25
Well you can find what it equals in terms of x. If you know that y plus y equals 25 to the power of 25 then you know that 2y=25^25 which means that y=(25^25)/2 - this is a huge number. To find x+y you just add x to what y equals so you get x+(25^25)/2
If 2+3 5s 5 squared is 25 then 25 times 2 equals 50
