a: \(=\dfrac{\left(5\cdot2^6+2^6\cdot3^2-2^6\cdot3\right)}{2^6}=5+9-3=2+9=11\)
b: \(=\dfrac{600}{450:\left[450-4\cdot125+8\cdot25\right]}\)
\(=\dfrac{600}{450:150}=\dfrac{600}{3}=200\)
c: \(=1500-\left\{125\cdot8-11\cdot\left(49-5\cdot8+8\cdot0\right)\right\}\)
\(=1500-\left\{1000-99\right\}=1500-901=599\)
