− 5 7 + 14 11 − 11 14 − 14 − 11 = − 5 7 − 11 14 = − 21 14 = − 3 2 .

Nhờ mọi người giúp mình với

     \(\left(128-49\right)+\left(-51-28\right)\)

\(=128-49-51-28\)

\(=\left(128-28\right)-\left(49+51\right)\)

\(=100-100=0\)

a) \(35\left(14-101\right)-14\left(35-10\right)\)

\(=35\cdot14-35\cdot101-14\cdot35+14\cdot10\)

\(=140-3535=-3395\)

b) \(5^2\cdot\left(-3\right)^3=25\cdot\left(-27\right)=-675\)

a,  35. ( 14 - 101 ) -  14 . ( 35 - 10 )
= 35 . 14 - 35 . 101 - 14 . 35 + 14 . 10

= 35 . 14 . ( - 35 . 101 - 14 . 10 )

= 490 . ( - 3535 - 140) 

= 490 . ( - 35675 ) 

~~ Tự tính nốt nhé

b, \(5^2.\left(-3\right)^3=25.\left(-27\right)\)= - 675

Sai đề k??

a)35.(14-101)-14.(35-10)

=35.14-35.101-14.35-14.10

=35.(14-101-14)-14.10

=35.(-101)-14.10

=-3535-140

=-3675

b)5².(-3)³=25.(-27)=-675

a: 86+357+14

=100+357

=457

b: \(3\cdot52-16:22\)

\(=156-\dfrac{8}{11}=\dfrac{1708}{11}\)

\(\left(\frac{-1}{4}+\frac{7}{33}-\frac{5}{3}\right)-\left(\frac{-5}{4}+\frac{6}{11}-\frac{48}{49}\right)=\left(\frac{-1}{4}-\frac{16}{11}\right)-\left(-\frac{31}{44}-\frac{48}{49}\right)=-\frac{1}{4}-\frac{16}{11}+\frac{31}{44}+\frac{48}{49}=-\frac{1}{49}\)

a) \(17+188+183=205+183=388\)

b) \(80-\left[130-\left(12-4\right)^2\right]\)

\(=80-\left(130-64\right)\)

\(80-66=14\)

c) \(2^3.17-2^3.14\)

\(8.17-8.14\)

\(=8.\left(17-14\right)\)

\(=8.3=24\)
