a: \(=35.5^2+64.5\left(71+64.5\right)=35.5^2+8739.75=10000\)
b: =16x102-64x17-16x34
=16(102-17x6)-16x34
=-16x34=-544
e: \(=\dfrac{5}{7}\left(\dfrac{40}{11}-\dfrac{117}{11}\right)=\dfrac{5}{7}\cdot\left(-7\right)=-5\)
f: \(=\dfrac{3}{7}\left(\dfrac{2}{5}+\dfrac{3}{5}\right)-\dfrac{10}{7}=\dfrac{3}{7}-\dfrac{10}{7}=-1\)
