Try -1.
x=1, x=-6
If: y2+x2 = 52 Then: x2 = 52-y2 Their values could be: x = 3 and y = 4
200
5 to the second power
It then equals 1/81
It equals 200 because 20x20 equals 200
no
If: y2+x2 = 52 Then: x2 = 52-y2 Their values could be: x = 3 and y = 4
4
14
200
5 to the second power
It then equals 1/81
It equals 200 because 20x20 equals 200
x2 + 5x = 6Subtract 6 from both sides:x2 + 5x - 6 = 0Factor:(x + 6)(x - 1) = 0The first value:x + 6 = 0, so x = -6The second value: x - 1 = 0, so x = 1The possible values of x are -6 and 1.
The answer is 1, whatever the value of a.
36
82 = 64.
