Có gì k hiểu thì ib nhá

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
