Question

24. 7+ 3.8.20 - 8.6.11 tính nhanh nhé

 

Answer 1

\(=24\cdot7+6\cdot8\left(10-11\right)\)

\(=24\cdot7-48=120\)

Answer 2

\(=24\cdot7+24\cdot20-24\cdot11=24\left(7+20-11\right)=24\cdot16=384\)

Answer 3

24. 7+ 3.8.20 - 8.6.11

= 8.3.7+3.8.20-8.3.11.2

=8.3.7+3.8.20-8.3.22

=8.3.(7+20-22)

hoặc

=24⋅7+6⋅8(10−11)=24⋅7+6⋅8(10−11)

=24⋅7−24.2

=24.5

=120
