a: \(\left(2^{17}+17^2\right)\cdot\left(9^{15}-3^{15}\right)\cdot\left(2^4-4^2\right)\)
\(=\left(2^{17}+17^2\right)\cdot\left(9^{15}-3^{15}\right)\cdot\left(16-16\right)\)
\(=\left(2^{17}+17^2\right)\cdot\left(9^{15}-3^{15}\right)\cdot0\)
=0
b: \(\left(8^{2017}-8^{2015}\right):\left(8^{2014}\cdot8\right)\)
\(=\frac{8^{2015}\left(8^2-1\right)}{8^{2015}}\)
\(=8^2-1=64-1=63\)
c: \(\left(1^3+2^3+3^4+4^5\right)\left(1^3+2^3+3^3+4^3\right)\left(3^8-81^2\right)\)
\(=\left(1^3+2^3+3^4+4^5\right)\left(1^3+2^3+3^3+4^3\right)\cdot\left(3^8-3^8\right)\)
=0
d: \(\left(2^8+8^3\right):\left(2^5\cdot2^3\right)\)
\(=\left(2^8+2^9\right):2^8\)
\(=2^8:2^8+2^9:2^8\)
=1+2
=3
