Answer 2

((-20)^7)^-7:((-20)^-6)8+2^-2+((-17)^-4)^-6:((-17)^-13)^-2-(1/17)^2

First, let's simplify the expression step by step:

1. (-20)^7 = -128000000 2. (-128000000)^-7 = -7.8125e-22 3. (-20)^-6 = 1/(-20)^6 = 1/64000000 4. -7.8125e-22 / (1/64000000) = -500000000000 5. 8+2^-2 = 8+1/4 = 8.25 6. (-17)^-4 = 1/(-17)^4 = 1/83521 7. ((1/83521)^-6) = 1/((1/83521)^6) = 1/(1.564227e+31) = 6.397853e-32 8. (-17)^-13 = 1/(-17)^13 = 1/(-893871739) = -1.119838e-10 9. (-1.119838e-10)^-2 = 1/(-1.119838e-10)^2 = 1/1.255538e-20 = 7.969696e+19 10. (1/17)^2 = 1/289

Now we can calculate the final expression:

-500000000000 + 8.25 + 6.397853e-32 - 7.969696e+19 - 1/289

This will give us the final result after performing the arithmetic operations.
