Bài 10:
\(=4,2\times100,21-0,21\times\left(2,3+1,9\right)\\ =4,2\times100,21-0,21\times4,2\\ =4,2\times\left(100,21-0,21\right)=4,2\times100=420\)
Tick mình nha <3
Bài 10:
=4,2×100,21−0,21×(2,3+1,9)=4,2×100,21−0,21×4,2=4,2×(100,21−0,21)=4,2×100=420=4,2×100,21−0,21×(2,3+1,9)=4,2×100,21−0,21×4,2=4,2×(100,21−0,21)=4,2×100=420
nhớ tick cho mik nhó
