Tính
a) (195 . 132 - 132 . 85) : 110
b) 100 : 17 + 53 : 17
c) 1895 : 5 - 1745 : 5
d) (864 . 48 - 432 . 96) : (864 . 48.132)
e) (16.17 - 5) : (16.16 + 11)
ghi cách làm nha
a, (195 . 132 - 132 . 85) : 110
\(=132\left(195-85\right):110\)
\(=132.110:110\)
\(=132\)

Ta có cách giải như sau:
\(\frac{864.48-432.96}{864.48.432}\)= \(\frac{432.2.48-432.86}{864.48.432}\)=\(\frac{432.96-432.96}{864.48.432}\)=\(\frac{0}{864.48.432}\)=\(0\)
Have a nice night!everyone.
864.48-432.96/864.48.432
=432.96-432.96/864.48.432
=0/864.48.432
=0
B=864x48-432x96/864x48x432
B=432x96-432x96/432x96x432
B=432x(96-96)/432x96x432
B=0/432x96x432
