a) \(\left(x-3\right)^{2022}=\left(x-3\right)^{2023}\)

\(\left(x-3\right)^{2022}\left(x-3-1\right)=0\)

\(\left(x-3\right)^{2022}\left(x-4\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=3\\x=4\end{matrix}\right.\)

b) \(\left(x+1\right)^{2024}+\left(x+1\right)^{2023}=2\)

\(\left[\left(x+1\right)^{2022}-1\right]\left[\left(x+1\right)^{2022}+2\right]=0\)

\(\Leftrightarrow x+1=1\)

\(\Leftrightarrow x=0\)

c) \(\left(x+3\right)^2+\left(x+3\right)=12\)

\(\left[\left(x+3\right)-3\right]\left[\left(x+3\right)+4\right]=0\)

\(x\left(x+7\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x=-7\end{matrix}\right.\)

a: \(18\cdot7+65:13\)

=126+5

=131

b: \(785-\dfrac{323+148}{3}+2781\)

\(=785+2781-\dfrac{471}{3}\)

=3566-157

=3409

c: \(703-\dfrac{140}{42+28}-17^6\cdot17^9:17^{13}\)

\(=703-\dfrac{140}{70}-17^2\)

\(=703-289-2\)

=703-291

=412

e: \(\left(2^3\cdot9^4+9^3\cdot45\right):\left(9^2\cdot10-9^2\right)\)

\(=\dfrac{9^3\left(2^3\cdot9+45\right)}{9^2\cdot\left(10-1\right)}=\dfrac{9^3}{9^3}\cdot\left(8\cdot9+45\right)\)

=72+45

=117
