\(\frac{864.48-432.96}{864.48.432}=\frac{432.2.48-432.2.48}{864.48.432}=\frac{0}{864.48.432}=0\)
\(=\frac{432x2x48-432x96}{846x48x432}\)
\(=\frac{432x96-432x96}{846x48x432}\)
\(=\frac{0}{846x48x432}\)
\(=0\)
\(\frac{864\cdot48-432\cdot96}{864\cdot48\cdot432}\)
\(=\frac{432\cdot2\cdot48-432\cdot96}{864\cdot48\cdot432}\)
\(=\frac{432\cdot96-432\cdot96}{864\cdot48\cdot432}\)
\(=\frac{96\cdot\left(432-432\right)}{864\cdot48\cdot432}\)
\(=0\)
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
y = 864 . 48 - 432.96 / 864.48.432
= 432 . 2 . 48 - 432 . 2 . 48 / 864 . 48 . 432
= 0 / 864 . 48 . 432
= 0
\(A=\frac{864\cdot48-432\cdot96}{864\cdot48\cdot432}=\frac{432\cdot2\cdot84-432\cdot2\cdot48}{864\cdot48\cdot432}=\frac{0}{864\cdot48\cdot432}=0\)
\(\frac{864.48-432.96}{864.48.432}=\frac{432.2.48-432.96}{864.48.432}=\frac{432.96-432.96}{864.48.432}=0\)
