\(A=-1436--1586+|-532|-\left(568+468\right)+1434.\)
\(=-1436+1586+532-1036+1434\)
\(=1080\)
\(1,=\left(-1436+1434\right)+\left(1586+532\right)-100\\ =-2-100+2118=2016\\ 2,B=\dfrac{2^6\cdot3^{12}\cdot2^{12}\cdot2^6\cdot3^6}{2^{12}\cdot2^9\cdot3^9\cdot3^9}=2^3=8\)
b)a) A = (-1436) - (-1586) + |-532| - (568+468) + 1434
A=-1436+1586+532-1036+1434
A=150+532-1036+1434=1080
b)B=\(\frac{18^6.2^{12}.4^3.9^3}{16^3.6^9.27^3}=\frac{2^6.3^{12}.2^{12}.2^6.3^6}{2^9.2^9.3^9.3^9}=\frac{2^{24}.3^{18}}{2^{18}.3^{18}}=2^6\)
a, (2015 + 49) - 15
= 2015 - 15 + 49
= 2000 + 49
= 2049
b, (2150 + 1969) - ( 150 + 969)
= 2150 - 150 + 1969 - 969
= 2000 + 1000
= 3000
c, 1568 - (100 + 68)
= 1568 - 68 - 100
= 1500 - 100
= 1400
d, (1586 + 2005) - 1586
= 1586 - 1586 + 2005
= 0 +2005
= 2005

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