Question

35x34+35x34+65x75+65x45 tính = cách hợp lí

Answer 1

35x34+35x34+65x75+65x45 

= (35 x 34 + 35 x 34) + (65 x 75 + 65 x 45)

= 35 x 34 x 2 + 65 x (75 + 45)

= 2380 + 65 x 120

= 2380 + 7800

= 10180

Answer 2

35x34+35x34+65x75+65x45 

= (35 x 34 + 35 x 34) + (65 x 75 + 65 x 45)

= 35 x 34 x 2 + 65 x (75 + 45)

= 2380 + 65 x 120

= 2380 + 7800

= 10180

Answer 3

Answer 4

35x34+35x34+65x75+65x45

= ( 35 x 34 + 35 x 34 ) + ( 65 x 75 + 65 x 45 )

= 35 x 34 x 2 + 65 x ( 75 + 45 )

= 2380          + 7800

= 10180

Answer 5

35x34+35x34+65x75+65x45

=35x(34+34)+65x(75+45)

=35x68+65x120

=2380+7800

=10180

Answer 6

35x34+35x34+65x75+65x45 

= (35 x 34 + 35 x 34) + (65 x 75 + 65 x 45)

= 35 x 34 x 2 + 65 x (75 + 45)

= 2380 + 65 x 120

= 2380 + 7800

= 10180

Answer 7

35x34+35x34+65x75+65x45 

= (35 x 34 + 35 x 34) + (65 x 75 + 65 x 45)

= 35 x 34 x 2 + 65 x (75 + 45)

= 2380 + 65 x 120

= 2380 + 7800

= 10180

Answer 8

\(\text{Tính bằng cách hợp lí : }\)

      \(35\text{ x }34+35\text{ x }34+65\text{ x }75+65\text{ x }45\)

\(=34\text{ x }\left(35+35\right)+65\text{ x }\left(75+45\right)\)

\(=34\text{ x }70+65\text{ x }120\)

\(=2380+7800\)

\(=10180\)
