Question

13* 27 + 13 * 70 + 13 * 4 - 13

 

Answer 1

13* 27 + 13 * 70 + 13 * 4 - 13

= 13* 27 + 13 * 70 + 13 * 4 - 13 x 1

= 13 * ( 27 + 70 + 4 - 1 )

= 13 * 100

= 1300

Answer 2

\(13\times27+13\times70+13\times4-13\)

\(13\times27+13\times70+13\times4-13\times1\)

\(=13\times\left(27+70+4-1\right)\)

\(=13\times100\)
\(=1300\)

Answer 3

13* 27 + 13 * 70 + 13 * 4 - 13

=13* 27 + 13 * 70 + 13 * 4 - 13*1

=13*(27+70+4-1)

=13*100

=1300

Answer 4

13*27 +13*70 +13*4-13

=13*(27+70+4)-13

=13*101-13

=1313-13

=1300

Answer 5

13 x 27 + 13 x 70 + 13 x 4 - 13

= 13 x 27 + 13 x 70 + 13 x 4 - 13 x 1

= 13 x ( 27 + 70 + 4 - 1 )

= 13 x 100

= 1300

Answer 6

13 * 27 + 13 * 70 + 13 * 4 -13 

= 13 * 27 + 13 * 70 + 13 * 4 - 13 * 1 

= 13 * ( 27 + 70 + 4 - 1 )

= 13 * 100 

= 1300

Answer 7

13 x 17 + 13 x 70 + 13 x 4 - 13 

= 13 x ( 17 + 70 + 4 - 1 ) 

= 13 x 100

= 1300 

đap số 1300

Answer 8

13 x 27 + 13 x 70 + 13 x 4 - 13

13 x 27 + 13 x 70 + 13 x 4-  13 x 1

13 x ( 27 + 7 + 4 - 1)

13 x 100

1300
