Question

tính bằng 2 cách

a, 25 x (4 + 6)

b, 34 x 11 - 34 x 5

Answer 1

a: =25x10=250

b: =34x6=204

Answer 2

a =25 x 10=250

b =34x(11-5)=34x6=204

Answer 3

a. 25 x 10 =250

 C2: 25 x4 + 25 x 6 = 250

b. 374 - 170 =204

 C2 : 34 x ( 11 -5 ) = 34 x 6 = 204

Answer 4

a: =25x10=250

b: =34x6=204

Answer 5

\(a.25\times\left(4+6\right)\)

C1: 

\(=25\times10=250\)

C2: 

\(=25\times4+25\times6=100+150=250\)

\(b.34\times11-34\times5\)

C1: 

\(=374-170=204\)

C2:

\(=34\times\left(11-5\right)=34\times6=204\)

Answer 6

a: C1 : \(=25\times10=250\)

C2: \(=25\times4+25\times6\\=100+150=250\)

b: C1: \(=374-170=204\)

C2: \(=34\times\left(11-5\right)\\ =34\times6=204\)
