tính nhanh
3.78× (200- 68 ) - 3.78 × ( 100- 68 )
15.3 × 9.55 + 9.45 × 15.3 + 15.3
ai giúp mk với mik sẽ tik cho người ấy
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

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, \(15,3.9,55+9,45.15,3+15,3\)
\(=15,3.\left(9,55+9,45+1\right)\)
\(=15,3.20\)
\(=306\)
