Question

mình cảm ơn ạ !

Answer 1

ơ kìa sao dài thế:((

Answer 2

\(i,=15\cdot8+4\cdot9-35=120+36-35=121\\ k,=4\cdot25-32:16=100-2=98\\ l,=35\left(38+82\right)+65\left(75+45\right)\\ =120\left(35+65\right)=120\cdot100=12000\\ m,=111+12=123\\ n,=72-25=47\\ o,=\left(25\cdot4\right)\cdot\left(7\cdot10\right)=100\cdot70=7000\\ p,=\left[504-\left(200+70\right):27+6\right]:125\\ =\left(504-10+6\right):125=500:125=2\)

Answer 3

=15.8+4.9-5.7

=120+36-35

=121

 

k)=4.25-32:16

   =100-2

   =98

l)=35.(38+82) + 65.(75+45)

= 35.100+65.100

=100.(35+65)

=100.100

=10000

m)=111+12

     =123

n)=2⁵-5²

  =32-25

   =7

o)=(25.4).(10.7)

    =100.70

    =7000

p)=[504-270:27+6]:125

   =500:125

    =4
