17,4 x 2 x 15 - 3,48 x 6 x 10 + 17,4 : 0,5

Các bạn giải nhanh giúp mk nhaaaaa

Answer 1

\(17,4\cdot2\cdot15-3,48\cdot6\cdot10+17,4:0,5\)

\(=17,4\cdot2\cdot15-17,4\cdot2\cdot6+17,4\cdot2\)

\(=17,4\cdot2\left(15-6+1\right)\)

\(=34,8\cdot10=348\)

Answer 2

17,4 x 2 x 15 - 3,48 x 6 x 10 + 17,4 : 0,5

=17,4x30-3,48x6x5x2+17,4x2

=17,4x30-17,4x6x2+17,4x2

=17,4x(30-6x2+2)

=17,4x20

=348

Answer 3

17,4×2×15-3,48×6×10+17,4:0,5

=(34,8×15)-(34,8×6)+(17,4×2)

=34,8(15-6+1)

=34,8×10

=348
