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
B=0
\(B=\frac{864.48-432.96}{864.48.432}\)
\(B=\frac{432.2.48-432.96}{432.2.48.432}\)
\(B=\frac{432.\left(48.2-96\right)}{432.2.48.432}\)
\(B=\frac{432.\left(96-96\right)}{432.2.48.432}\)
\(B=\frac{432.0}{432.2.48.432}\)
\(B=\frac{0}{432.2.48.432}\)
\(B=0\)
