\(A=-1436--1586+|-532|-\left(568+468\right)+1434.\)
\(=-1436+1586+532-1036+1434\)
\(=1080\)

\(A=-1436-\left(-1586+532\right)-\left(568+468\right)+1434\)
\(A=-1436-\left(-1054\right)-1036+1434\)
\(A=-382-1036+1434\)
\(A=-1418+1434\)
\(\Rightarrow A=16\)
Vậy \(A=16\)

b)a) A = (-1436) - (-1586) + |-532| - (568+468) + 1434
A=-1436+1586+532-1036+1434
A=150+532-1036+1434=1080
b)B=\(\frac{18^6.2^{12}.4^3.9^3}{16^3.6^9.27^3}=\frac{2^6.3^{12}.2^{12}.2^6.3^6}{2^9.2^9.3^9.3^9}=\frac{2^{24}.3^{18}}{2^{18}.3^{18}}=2^6\)
