a: \(A=77^2+77\cdot22+77=7700\)
b: \(B=2\cdot\left(1.007+0.006\right)+2\left(-0.006-1.007\right)\)
\(=0\)
c: \(C=\left(x-1\right)\left(x^2-4x+4\right)\)
\(=\left(x-1\right)\left(x-2\right)^2=\left(3-1\right)\cdot\left(3-2\right)^2=2\)
d: \(D=\left(-5\right)^2\cdot2-2+\left(-5\right)\cdot2^2+5\)
\(=25\cdot2-2-5\cdot4+5\)
=50-2-20+5
=55-22=33
