Bài làm:

Có lẽ ý bạn là: Tính  \(C=1-2^3+2^6-2^9+...+2^{96}-2^{99}\)

Ta có: \(8C=2^3-2^6+2^9-2^{12}+...+2^{99}-2^{102}\)

\(\Rightarrow8C+C=\left(1-2^3+2^6-...-2^{99}\right)+\left(2^3-2^6+2^9-...-2^{102}\right)\)

\(\Leftrightarrow9C=1-2^{102}\)

\(\Rightarrow C=\frac{1-2^{102}}{9}\)

Để 2a41b chia hết cho 45, thì 2a41b phải chia hết cho 5 và cho 9

\(\Rightarrow\orbr{\begin{cases}b=0\\b=5\end{cases}}\)

Nếu b=0 thì a=2 để 2a41b chia hết cho 9

Nếu b=5 thì a=6 để 2a41b chia hết cho 9

Vậy: \(\left(a,b\right)\in\left\{\left(2;0\right);\left(6;5\right)\right\}\)
