\(15.30+15.73-15.13=15.\left(30+73-13\right)=15.90=1350\)

\(5^2.165-56.5^2=5^2.\left(165-56\right)=5^2.109=2725\)

\(=55:\left\{400:144\right\}=55:2,7=20,3\)

85 : 14 = 6,0714 ...

15,30 : 27,8 = 0,5503 ...

197 : 452,3 = 0,4355 ...

24 : 1,8 = 13,3333 ...

\(85\div14=6,0714...\)

\(15,30\div27,8=0,5503...\)

\(197\div452,3=0,4355...\)

\(24\div1,8=13,3333...\)

3,78 x ( 200 - 68 ) - 3,78 x ( 100 - 68 )

= 3,78 x 132 - 3, 78 x 32

= 3,78 x ( 132 - 32 )

= 3 , 78 x 100

= 378

15, 3 x 9,55 + 9,45 x 15 , 3 + 15 , 3

= 15,3 x ( 9.55 + 9.45 + 15.1 )

= 15,3 x 34.1

= 521.73

mk sợ câu thứ 2 chưa chắc đúng đâu nha câu nhờ ai giúp câu 2 nhé ^^

a, \(3,78.\left(200-68\right)-3,78.\left(100-68\right)\)

\(=3,78.132-3,78.32\)

\(=3,78.\left(132-32\right)\)

\(=3,78.100\)

\(=378\)

b, \(15,3.9,55+9,45.15,3+15,3\)

\(=15,3.\left(9,55+9,45+1\right)\)

\(=15,3.20\)

\(=306\)
