121 is 11 to the second power 361 is 19 to the second power 576 is 24 to the second power 1000 does not belong because no number to the second power = 1000
(9n2 - 121) = (3n + 11) (3n - 11)
121 = (11)2
x2 + 121y2 = x2 - (-121)y2 = x2 - (11iy)2 = (x - 11iy)(x + 11iy)
The answer is 121 Since 11^2 = 11*11 = 121
121 is 11 to the second power 361 is 19 to the second power 576 is 24 to the second power 1000 does not belong because no number to the second power = 1000
eleven to the second power means eleven times eleven. the answer is 121.
If x^2 = 121 then the value of x is 11
112 = 11 x 11 = 121
112 = 121
(9n2 - 121) = (3n + 11) (3n - 11)
121 to the 8th power is 45,949,729,863,572,161
121 = (11)2
112 = 121 so [sqrt(11)]4 = 121 That is, ± 3.317 (approx) to the power 4 equals 121
(20-1-6-2)2 = 112 = 121
112 = 121
x2 + 121y2 = x2 - (-121)y2 = x2 - (11iy)2 = (x - 11iy)(x + 11iy)
