\(A=-1436--1586+|-532|-\left(568+468\right)+1434.\)
\(=-1436+1586+532-1036+1434\)
\(=1080\)
\(A=-1436-\left(-1586+532\right)-\left(568+468\right)+1434\)
\(A=-1436-\left(-1054\right)-1036+1434\)
\(A=-382-1036+1434\)
\(A=-1418+1434\)
\(\Rightarrow A=16\)
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=\(\frac{18^6.2^{12}.4^3.9^3}{16^3.6^9.27^3}=\frac{2^6.3^{12}.2^{12}.2^6.3^6}{2^9.2^9.3^9.3^9}=\frac{2^{24}.3^{18}}{2^{18}.3^{18}}=2^6\)
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)\(568-\left\{5.\text{[}143-\left(4-1\right)^2\text{]}+10\right\}:10\)
\(=568-\left\{5.\left[143-3^2\right]+10\right\}:10\)
\(=568-\left\{5.134+10\right\}\text{ }\)
\(=568-\left(670+10\right)\)
\(=568-680\)

b)\(10^2-\left[60:\left(5^6:5^4-3\times5\right)\right]\)
\(=100-\left[60-\left(6^2-15\right)\right]\)
\(=100-\left(60-\left(36-15\right)\right)\)
\(=100-60-36+15\)
