1 to any integral power is 1.
1/12 = 1/1=1
(-1)2 = +1
If you raise the number 1 to ANY power, you get 1.
(-1)2 = (-1) x (-1) = 1
5
28 to the 2nd power
1/16
Negative 9 to the negative 2nd power (-9-2) = 0.012345679 (repeating).
1 over 3 to the negative 2nd power is 9
a2/a6 = 1/a4
It is 1/36.
Factor them. k2 = k x k k2 - 1 = (k - 1)(k + 1) k2 - 2k + 1 = (k - 1)(k - 1) Combine the factors, eliminating duplicates. k2(k + 1)(k - 1)(k - 1) = k5 - k4 - k3 + k2, the LCM
