Answer 1

   673 . 54 + 673 . 45 + 673 

= 673 . 54 + 673 . 45 + 673 .1 

= 673 . ( 54 + 45 + 1 )

= 673 . 100 

= 67300

Answer 2

673x54+673x45+673

=673x(54+45+1)

=673x100

=67300

Answer 3

Ta có :

\(673.54+673.45+673\)

\(=\)\(673\left(54+45+1\right)\)

\(=\)\(673.100\)

\(=\)\(67300\)

Answer 4

673 x 54 + 673 x 45 + 673

= 673 x 54 + 673 x 45 + 673 x 1

= 673 x ( 54 + 45 + 1 )

= 673 x 100

= 67300

Answer 5

673 x 54 + 673 x 45 + 673

= 673 x 54 + 673 x 45 +673 x 1

= 673 x ( 54 + 45 + 1 )

= 673 x 100

= 673

Answer 6

673 x 54 + 673 x 45 + 673 

= 673 x 54 + 673 x 45 + 673 x 1 

= 763 x ( 54 + 45 + 1 ) 

= 763 x 100 

= 76 300

Chúc bạn Tết vui vẻ !

Answer 7

= 673 * (54+45+1)
