[15:(-3)+40:(-8)].3(16:8)

-[-171+(171+23)]-[172-(38+172)]-49

giúp mik vs :3

Answer 1

\(2\cdot\left|-5\right|\cdot\left|-3\right|-4-4\cdot(25:5)+\left|-4\right|\)

\(=2\cdot5\cdot3-4-4\cdot5+4\)

\(=30-4-4\cdot5+4=30-4-20+4=10\)

Answer 2

Trả lời

Ko ghi lại đề

=2.5.3-4-4.(25:5)+4

=30-4-20+4

=10

Ko ghi lại đề

=(-5)+(-5).5

=-50

Ko ghi lại đề

=+171-171-23-172-38+172-49

=-23-38-49

=-110

Ko chắc câu cuối !

Answer 3

\(\left[15:(-3)+40:(-8)\right]\cdot3(16:8)\)

\(=\left[(-5)+(-5)\right]\cdot3\cdot2\)

\(=-10\cdot6=-60\)

Answer 4

\(-\left[-171+(171+23)\right]-\left[172-(38+172)\right]-49\)

\(=-\left[-171+194\right]-\left[172-210\right]-49\)

\(=-23-(-38)-49=-34\)
