\(C_1\)\(50-20:5+50-32:2\)
\(=50-4+50-16\)
\(=46+34\)
\(=80\)
\(C_2\) \(50-20:5+50-32:2\)
\(=50-4+50-16\)
\(=\left(50+50\right)-\left(4+16\right)\)
\(=100-20\)
\(=80\)
P/s : Mik ko chắc
~ Ủng hộ nhé
50 - 20 : 5 + 50 - 32 : 2
= 50 - 4 + 50 - 16
= 46 + 50 - 16
= 96 - 16
= 80
Cách 1:
\(50-20:5+50-32:2\)
\(=50+50-20:5-32:2\)
\(=\left(50+50\right)-4\times5\times\frac{1}{5}-4\times4\times2\times\frac{1}{2}\)
\(=100-4-4\times4\)
\(=100-4\times\left(1+4\right)\)
\(=100-4\times5\)
\(=100-20\)
\(=80\)
Cách 2:
\(50-20:5+50-32:2\)
\(=(50-4)+(50-16)\)
\(=46+34\)
\(=80\)
Cách 1 :
50 - 20 : 5 + 50 - 32 : 2
= 50 - 4 + 50 - 16
= 46 + 50 - 16
= 96 - 16
= 80
Cách 2 :
50 - 20 : 5 + 50 - 32 : 2
= 50 - 4 + 50 - 16
= ( 50 + 50 ) - ( 4 + 16 )
= 100 - 20
= 80
