It's 1/64. Negative power means it goes in the denominator. so 8-2=1/(82)=1/64
(x^2 - 2x + 2)(x^2 + 2x + 2)
(-2)^4 = -2 x -2 x-2 x-2 = +16 ( a minus times a minus is plus)

49 - 8 - 6 = 35
5 to the power of 2
49 - 8 - 6 = 35
3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.
