\(17\times37+34\times33-51\)
\(=17\times37+17\times2\times33-17\times3\)
\(=17\times37+17\times66-17\times3\)
\(=17\times\left(37+66-3\right)\)
\(=17\times100\)
\(=1700\)

Trả lời :
17 . 37 + 34 . 33 - 51
= 17 . 37 + 17 . 66 - 17 . 3
= 17 . (37 + 66 - 3)
= 17 . 100
= 1700
17 x 37 + 34 x 33 - 51
= 17 x 37 + 17 x 2 x 33 - 17 x 3
= 17 x 37 + 17 x 66 - 17 x 3
=17 x ( 37 + 66 - 3)
= 17 x 100
= 1700
17 x 37 + 34 x 33 - 51
= 17 x 37 + 17 x 2 x 33 - 17 x 3
= 17 x 37 + 17 x 66 - 17 x 3
= 17 x ( 37 + 66 - 3)
= 17 x 100
= 1700
